Property Management Software
Property Management Tools Built for Every Rental Property Type
Most landlord software handles one property type and ignores the rest. We built tools for all of them — because real landlords own all kinds.
Most landlord software handles one property type and ignores the rest. We built tools for all of them — because real landlords own all kinds.
There's something most landlord software companies don't admit: their tool only works for one type of property. The Airbnb tool ignores your duplex. The apartment software has no idea what to do with a mobile home park. The commercial real estate platform doesn't track who paid rent on the bedroom you rent out in the basement.
Real landlords accumulate properties. They start with a single rental house, buy a fourplex, take over a vacation rental, inherit a commercial space from a parent, get into a sober living investment with a partner. By the time they have any real portfolio, the typical software they started with is choking on what they own now.
Underground Landlord built tools for every type of rental property. Not as an afterthought. As the entire point.
Multi-unit residential — buildings, units, leases, ledgers
Retail, office, warehouse, industrial, mixed-use
Mobile home parks — lots, homes, owner financing
SFH rentals — properties, tenants, repairs, P&L
Airbnb / VRBO — guests, profitability, STR vs LTR
Per-room rent, sober living, boarding, motels
Universal tenant tracker + tax center across all property types
Most property management software does one thing well and forces you to build workarounds for everything else. We took a different approach: build separate, dedicated tools for each property type that share data through one universal tenant management layer.
That means apartment software that actually understands apartments. Commercial software that understands CAM charges. Mobile home park software that understands lot rent versus home rent versus owner-financed sales. STR software that compares short-term rental performance against what you'd make as a long-term rental.
The kinds of problems we built for didn't come from a software roadmap. They came from landlords. The investor who can't track which of their three apartment buildings is actually profitable. The mobile home park owner who's running a spreadsheet for lot rent and a separate spreadsheet for the homes they own. The Airbnb host who has no idea whether their vacation rental is actually beating what a long-term tenant would pay.
Each tool was built to fix specific problems specific landlords kept running into. The result is software that fits the actual shape of how landlords operate — across property types, across financing arrangements, across tenant types.
Once you have any real rental portfolio, taxes become a major event. Schedule E filings. Depreciation schedules. 1031 exchanges. Passive loss carryforwards. Mileage logs. Most landlord software handles none of this and leaves you paying a CPA thousands of dollars to assemble what your software should have tracked all year.
The Tenant Management Compilation includes a tax center that handles all of it — Schedule E ready for your CPA, depreciation schedules, 1031 exchange tracking, passive loss carryforward, QBI hours. The CPA still files. They just don't have to spend twenty hours figuring out what's in your portfolio.
Most landlords start with whichever tool fits the property type they have most of. Single family rentals? Start with Single Family Homes Master. Apartment complex? Start with Apartment Manager. Vacation rental? Sharp Vacation Manager. Then add Tenant Management Compilation once you want the universal view across everything.
The tools don't require a contract, don't replace your accountant, and don't try to be everything for everyone. They just do the property-management work that real landlords have been cobbling together with spreadsheets and patience for too long.
