Property Management Software for Small Landlords: Build or Buy?

For most landlords with under 50 units, buy, don't build: an off-the-shelf tool costs a few hundred to a few thousand dollars a year, while a custom property management MVP starts around $9,000. Of the two tools compared here, AppFolio's Core plan has a 50-unit minimum, and Buildium's Essential plan starts at $62 a month. Build only if software for landlords is your business.

This guide is for two readers: independent landlords with 1 to 50 units deciding what to use, and founders deciding whether to build a product for those landlords. RAITHub builds software, so it has a reason to say "build"; for most landlords reading this, it doesn't. How to build the product, once you have decided to, is covered in property management software development. Vendor prices below are quoted from each vendor's own pricing page, checked on 29 September 2026.

Should a small landlord build or buy property management software?

Buy, unless the software is the product you sell. A landlord's edge is the properties, the tenants and the service, not the rent ledger, and every mainstream tool already handles rent, leases and maintenance requests.

Your situation	Usually the better fit	Why
1 to 5 units, one owner	Spreadsheet plus bank transfer, or a low-cost tool	The admin is small; the fees and set-up of a platform may not pay back
5 to 50 units, residential, US-based	An off-the-shelf tool built for small portfolios	Rent, leases, maintenance and reporting exist and are maintained for you
50+ units, or growing fast	A tool whose plans are designed for your size	Plan minimums and onboarding make more sense at scale
Unusual workflow no tool fits (by-the-room lets, mixed use, a local market tools don't serve)	Try tools first; build a narrow add-on if one rule is missing	Rebuilding a whole platform for one rule is rarely worth it
You are building a product to sell to landlords	Build	The software is the business, so owning it is the point

AppFolio vs Buildium: which fits under 50 units?

On their own published terms, Buildium's Essential plan is priced for small portfolios, and AppFolio's Core plan sets a 50-unit minimum. That makes the choice under 50 units simpler than it looks.

What the pricing page says	AppFolio Property Manager	Buildium
Entry plan	Core	Essential
Published entry price	Not published; "contact us for details"	Starting at $62 a month, billed monthly
Unit minimum	"Minimum spend and 50 unit minimum apply" on Core	None stated for Essential
Higher plans	Plus and Max; "minimum spend and units apply"	Growth from $192 a month; Premium from $400 a month
Incoming rent by bank transfer (EFT)	Not published	$2.35 per transaction on Essential; $1.35 on Growth
Card payments	Not published	2.99% per transaction

How to read it. If you have fewer than 50 units, AppFolio's Core plan, as advertised, is outside your size; ask AppFolio directly whether that applies to you. Buildium's Essential plan publishes a price and has no stated unit minimum, so you can model its cost yourself. Neither vendor is the only option, and comparing three tools on price per unit, payment fees and plan minimums before you commit costs you an afternoon.

What does an off-the-shelf tool really cost over three years?

More than the subscription, because rent payments carry their own fees. Here is the arithmetic for a 20-unit landlord on Buildium Essential, using its published prices, if every tenant pays by bank transfer and the landlord absorbs the fee.

Cost line	Per year	Over 3 years
Subscription at $62 a month	$744	$2,232
Incoming EFT: 20 units × 12 payments × $2.35	$564	$1,692
Bank account set-up, once, at $99	$99 in year one	$99
Total	About $1,407 in year one	About $4,023

This is an illustration, not a quote: the "starting at" price may change with your portfolio, and tenants paying by card change the fee line. The point is the order of magnitude. Three years of a ready-made tool for 20 units costs roughly $4,000.

A custom build starts far higher. Published 2026 guides put a basic custom property management MVP at $9,000 to $22,000 and a full platform at $70,000 to $140,000 or more (Saigon Technology, September 2026). Those are market figures, not RAITHub prices, and they exclude hosting, payment fees and the developer time every live product needs after launch. For one landlord, building would cost several times more than three years of a tool, before it earns anything back.

Is a spreadsheet enough for a few units?

Often, yes, for 1 to 5 units with one owner. A spreadsheet with one row per charge and one per payment, a bank account used only for rent, and calendar reminders for lease renewals will carry a small portfolio a long way.

It stops working at predictable points:

• Late rent becomes a routine. Reminders and late fees that depend on you remembering get missed.
• Maintenance requests arrive by text and get lost. There is no record of who reported what and when.
• A deposit dispute needs evidence. Move-in photos in a phone gallery are hard to produce a year later.
• Someone else helps you. A partner, a handyman or an assistant needs access to part of the picture, not all of it.

Those are the same problems PropDesk, the property management platform RAITHub built, was specified around: spreadsheets that break as units grow, rent reminders done by hand, maintenance requests lost between people, and disputes without documentation. When two of them apply to you, it is time for a tool.

When does building your own property management software make sense?

In two cases: when you are building a product for other landlords, or when one rule no tool supports is costing you real money. In the second case, build the missing piece, not a whole platform.

You are building a product for small landlords

If the software is what you sell, owning it is the point, and the question becomes how to scope the first version. PropDesk is the example: a property management platform RAITHub built for the 1 to 50 unit market, from a 122-page software requirements specification. Its published numbers are 130+ API endpoints, 60+ pages, 29 database models, 4 user roles (landlord, tenant, contractor and admin), 5 daily automation jobs, and 1,024 automated tests, 932 unit and 92 end to end (PropDesk case study). That is several releases of work, which is why a first version must be much narrower.

One rule is missing from your tool

Keep the tool, and build a small service or report alongside it, if its API or exports allow that. Rebuilding rent, leases, maintenance and accounting to fix one gap trades a small problem for a large one.

What should a first version for small landlords include?

For a founder building the product, the first release should do three things well: collect rent against a lease, record every charge and payment, and route maintenance to the right person. Everything else can wait for paying users to ask for it.

Release	Include	Why then
First release	Properties and units, leases, online rent collection, a ledger, maintenance requests, landlord and tenant portals	This is what a landlord pays for on day one
Second release	Rent reminders, late fees on a grace period, lease expiry alerts, contractor portal, move-in/out inspections	Automation and evidence, once real tenants are using it
Later	Items like those on PropDesk's own roadmap: tenant screening, e-signatures, bank connection through Plaid, SMS notifications, owner and investor portals	Each depends on a partner integration and real demand

A focused first release of this kind is usually a fixed 4 to 6 week build at RAITHub, and rent, lease and scheduling backends 6 to 12 weeks. For a quick range on your own scope, use the MVP cost estimator; the wider cost drivers are in the cost to build a real estate platform, and the product types beyond property management are in the PropTech software development guide.

Why RAITHub for this, and when you don't need us

RAITHub built PropDesk for exactly this market and published its numbers, so a founder can judge the work before a call. First releases are built under MVP development as fixed-scope projects, quoted in writing after a free 15-minute technical audit, with a dedicated team month-to-month if the product keeps growing. You own the code, and an NDA is standard.

You don't need RAITHub if:

• You are a landlord looking for a tool to use. Buy one. Compare three on price per unit, payment fees and the features you will actually use.
• You need a trust-accounting system designed by someone who has shipped one. PropDesk is not proof of that.
• You need legal advice on deposits, notices or fees. RAITHub builds workflows; the rules come from you and your adviser.
• You want developers placed in your team, or a certified vendor. RAITHub does not offer staff augmentation and is not SOC 2 or ISO 27001 certified.

If you are building a product for small landlords, book the free 15-minute technical audit with your first-release scope and how rent will move. The PropTech page sets out what a build includes.

Frequently asked questions

What property management software is good for small landlords?

One priced for your portfolio size, with online rent collection, leases, maintenance requests and simple reporting. Compare at least three tools on price per unit, payment fees and plan minimums. Under 50 units, check each plan's unit minimum before you book a demo.

Is AppFolio or Buildium better for under 50 units?

On published terms, AppFolio's Core plan states a 50-unit minimum and does not publish prices, while Buildium's Essential plan starts at $62 a month with no stated unit minimum. Confirm with both vendors, as plans change.

How much does property management software cost for 20 units?

Using Buildium Essential's published prices as an example, about $4,000 over three years: $62 a month, $2.35 per incoming bank payment if the landlord absorbs it, and a one-off $99 bank account set-up. Card payments cost more.

Should a landlord build their own property management software?

Rarely. A basic custom MVP is quoted at $9,000 to $22,000 in published 2026 guides, several times more than years of an off-the-shelf tool. Build when software for landlords is the business you are starting.

What features do small landlords need first?

Online rent collection against each lease, a record of every charge and payment, maintenance requests with status, and lease and document access for tenants. Reminders, late fees and inspections come next.

Did RAITHub build PropDesk?

Yes. RAITHub built PropDesk, a property management platform for landlords with 1 to 50 units, with Stripe rent collection, 4 user roles, 5 daily automation jobs and 1,024 automated tests.
