Property Management Software Cost: 3-Year SaaS vs Custom

Off-the-shelf property management software in the US costs from $25 to a few hundred dollars a month, plus payment fees. Over three years, a 100-unit manager on Buildium's Growth list price spends about $11,800 before onboarding. A basic custom build costs roughly $34,000 to $55,000 over the same period once hosting, payment fees and upkeep are counted, so custom rarely wins on cost alone.

This guide is for property managers with 20 to 300 units weighing whether to keep paying for a tool or build their own, and for founders pricing a product for that market. Vendor prices are quoted from each vendor's pricing page, checked on 30 September 2026; build figures are published market ranges, not RAITHub quotes. Where a number is an assumption, the table says so.

How much is property management software per month?

Published US prices run from a free plan to a few hundred dollars a month, and the biggest vendors quote on request. The subscription is only one line; payment fees are the other.

Vendor and plan	Published price	Payment fees on the same page
Rentec Direct Starter	A flat $25 a month, 10 or fewer properties	ACH $2 per transaction; cards 2.95% to 3.50%
Rentec Direct Pro and PM	From $50 a month, rising with units	ACH free; cards 2.95% to 3.50%
Buildium Essential	From $62 a month	Incoming EFT $2.35; cards 2.99%
Buildium Growth	From $192 a month; onboarding required	Incoming EFT $1.35; cards 2.99%
Buildium Premium	From $400 a month; onboarding required	Incoming EFT free for 12 months, then $0.60; cards 2.99%
AppFolio Core, Plus, Max	Not published; "Minimum spend and 50 unit minimum apply" on Core	Not published

Is custom property management software cheaper than SaaS over 3 years?

Almost never for a manager running their own portfolio. The build alone costs more than three years of a tool, and a custom system then adds hosting, payment processing and the developer time every live product needs.

The table compares three years for an illustrative 100-unit portfolio with every tenant paying monthly by bank transfer. The SaaS column uses Buildium Growth's list prices because they are published; AppFolio's are not. Build ranges are from Saigon Technology's 2026 property management guide. Hosting, upkeep and payment volumes are assumptions, labelled as such.

3-year cost line (100 units)	SaaS: Buildium Growth, list price	Custom: basic MVP	Custom: full platform
Subscription or build	$192 × 36 months = $6,912	$9,000 to $22,000	$70,000 to $140,000
Onboarding	Required; price not published	Included in the build	Included in the build
Rent by bank transfer, 3,600 payments	$1.35 each = $4,860	Stripe ACH at its $5 cap = $18,000	Stripe ACH at its $5 cap = $18,000
Hosting and database (assumption)	Included	$50 a month = $1,800	$100 a month = $3,600
Upkeep and small changes (assumption: 20% of build a year)	Included	$5,400 to $13,200	$42,000 to $84,000
3-year total	About $11,800 plus onboarding	About $34,200 to $55,000	About $133,600 to $245,600

How the payment line is worked out: Stripe's standard US price for ACH Direct Debit is 0.8% with a $5.00 cap (Stripe pricing), so any rent above $625 hits the cap. Stripe also offers custom pricing at volume, and many landlords pass fees to tenants, which would shrink that line on both sides. Hosting assumes a small serverless app, such as Vercel Pro at $20 a month (Vercel pricing) with a usage-billed Postgres database such as Neon, which has no monthly minimum on its paid plans (Neon pricing). The 20% upkeep figure is a planning assumption, not a benchmark: security updates, dependency upgrades, fixes and small requests from staff.

The lesson is not that custom software is expensive. It is that SaaS vendors spread the cost of building, hosting and maintaining across thousands of customers, and negotiate payment rates you would have to negotiate yourself.

Why do payment fees matter more than the subscription?

Because they scale with every rent payment, every month, and the subscription does not. In the table above, Buildium's EFT fees are 70% of the size of its three-year subscription, and on a custom build the uncapped-volume payment line is the largest single running cost.

• Decide who pays. Absorbing a $2 fee across 100 units is $2,400 a year. Passing it to tenants costs nothing but needs to be allowed by your leases and local rules; confirm that with your adviser.
• Steer tenants to bank transfer. Card fees near 3% on a $1,500 rent are about $45 a payment, many times a bank fee.
• Price the failure path. Returned bank payments, disputes and retries have their own fees and their own staff time.
• On custom builds, model the payment provider first. The provider's pricing, not the code, often decides whether a build pays back. How rent flows through Stripe in a custom build is covered in building online rent collection.

How do I work out my own 3-year total cost of ownership?

Add the fixed costs, the per-payment costs and the people costs for each option over the same 36 months, using your own unit count and payment mix. A few lines of code, or a spreadsheet, is enough.

type Option = {
  upfront: number          // build price, or onboarding for SaaS
  monthlyFixed: number     // subscription, or hosting for custom
  feePerPayment: number    // average fee per rent payment
  yearlyUpkeep: number     // 0 for SaaS; developer time for custom
  staffHoursPerMonth: number // manual work the tool leaves you
}

export function threeYearTco(o: Option, units: number, hourlyCost: number): number {
  const months = 36
  const payments = units * months
  return (
    o.upfront +
    o.monthlyFixed * months +
    o.feePerPayment * payments +
    o.yearlyUpkeep * 3 +
    o.staffHoursPerMonth * hourlyCost * months
  )
}

// Buildium Growth list price, 100 units, bank transfer, 20 manual hours a month at $30:
// threeYearTco({ upfront: 0, monthlyFixed: 192, feePerPayment: 1.35,
//   yearlyUpkeep: 0, staffHoursPerMonth: 20 }, 100, 30)  // 33,372

The last input is the one most comparisons leave out. If a tool forces 20 hours a month of manual work, re-keying owner statements or chasing maintenance by phone, that is $21,600 over three years at an assumed $30 an hour, nearly twice the tool itself. A custom add-on that removes those hours changes the answer, even though a full custom platform would not. The MVP cost estimator gives a quick range for the build line.

When does building your own property management software pay off?

In two situations, and neither is "the subscription feels expensive".

1. The software is the product you sell

If you are building for other landlords or managers, the build is an investment recovered from your customers' subscriptions, not a cost your own portfolio has to carry. PropDesk is the example RAITHub can point to: a property management platform built for landlords with 1 to 50 units, with Stripe rent collection, 4 user roles, 5 daily automation jobs, 130+ API endpoints and 1,024 automated tests (PropDesk case study). A first release is much narrower than that; the scope is in property management software development.

2. A gap costs more than a small build

When the manual work your tool leaves behind costs more each year than building the missing piece, build the piece, not a platform. Keep the SaaS for rent, leases and accounting, and add a service that reads its API or exports: an owner report, a maintenance intake flow, a room-by-room rent split. Scoped narrowly, this is a fixed-price job of weeks, and it keeps the vendor maintaining everything else.

Signals that point towards building

• You manage a segment the tools model badly: co-living rooms, student beds, mixed commercial and residential.
• You have outgrown per-unit pricing and the next tier requires onboarding, minimums and a migration anyway.
• Your data needs to feed another system you own, and the vendor's API doesn't expose it.
• You plan to sell the workflow to others within two years.

What costs do custom build quotes usually leave out?

Four lines are missing from most build quotes, and each can be larger than expected. Ask for them in writing before you compare a quote with a subscription.

Often-missing line	Why it matters	What to ask
Payment processing	Largest running cost at 100+ units	Which provider, which rail, who pays the fee
Upkeep after launch	Dependencies, security fixes and staff requests never stop	What a month of support costs, and what it covers
Data migration	Opening balances and deposits must reconcile on day one	Who migrates, and how the result is checked
Accounting integration	Your accountant still needs reports in their format	Export or sync to your accounting tool, and which reports

How to compare fixed-price and hourly quotes for this kind of build is in fixed price vs time and materials, and the running costs of any SaaS product, hosting through monitoring, are broken down in what a SaaS costs to run per month.

Why RAITHub for this

• Property management has been built. PropDesk covers Stripe rent collection with automated late fees and payment plans, maintenance routed to contractors, the lease lifecycle and inspections, with 1,024 automated tests.
• Quotes list the lines above. RAITHub's written fixed quote itemises payment flows, scheduled jobs, migration and integrations with their assumptions, so you can put it next to a subscription honestly.
• Add-ons are welcome. If the answer is "keep the tool, build one piece", RAITHub quotes the piece.
• US hours covered. From Dhaka (UTC+6), RAITHub offers US and Canada clients a daily 2-hour evening overlap, Dhaka 19:00 to 21:00, which is US East mornings. The working week is agreed per client, with written daily handoffs.
• Your code, your IP. An NDA is standard and all IP is assigned to you.

When you don't need us

• You manage your own units and a tool fits. Keep paying for it. The table above is the reason.
• Your problem is price, not fit. Negotiate with your vendor, change plan, or change who pays payment fees before you consider a build.
• You need trust accounting built by someone who has shipped one. PropDesk is not proof of that.
• You need tax, fee or tenancy law advice. RAITHub builds the workflow; your adviser supplies the rules.
• You want developers billed by the hour inside your team. RAITHub offers fixed-scope builds and dedicated monthly teams, not staff augmentation.

If you are building for this market, or want one missing piece priced against your subscription, see the MVP development service and how RAITHub prices work, then book the free 15-minute technical audit with your unit count, your current tool and its monthly bill, and the manual work it leaves you.

Frequently asked questions

How much is property management software per month?

Published US plans run from a free tier up to a few hundred dollars a month. Rentec Direct Starter is $25 a month for 10 or fewer properties, and Buildium's plans start at $62, $192 and $400 a month. AppFolio does not publish prices. Payment fees are charged on top.

Is custom property management software cheaper than AppFolio?

For a manager running their own portfolio, almost never over three years. AppFolio publishes no prices, so get a quote and compare it with a custom build's full cost: build, hosting, payment fees and upkeep. A basic custom build alone is quoted at $9,000 to $22,000 in published guides.

What does property management software cost over 3 years for 100 units?

Using Buildium Growth's list price and bank-transfer rent, about $11,800 plus onboarding: $6,912 in subscription and $4,860 in EFT fees. An illustrative basic custom build comes to about $34,200 to $55,000 over the same period.

What are the hidden costs of custom property management software?

Payment processing, upkeep after launch, data migration and accounting integration. Payment fees are often the largest: at Stripe's standard ACH price of 0.8% capped at $5, 100 units paying monthly cost up to $6,000 a year unless you negotiate or pass fees on.

When does it make sense to build property management software?

When the software is the product you sell to other landlords, or when a gap in your tool costs more each year than building the missing piece. In the second case, build an add-on beside the tool rather than a whole platform.

How much does it cost to build property management software?

Published 2026 guides put a basic custom MVP at $9,000 to $22,000 and a full platform at $70,000 to $140,000 or more. These are market figures. RAITHub gives a written fixed quote after a free 15-minute technical audit.
