From your first door to your hundredth.
Properties, tenants, rent, loans, rehabs and refinances in one place. Always know what you own, what you owe, and when you can buy the next one.
$19/mo for as long as you stay, instead of $29. Nothing to pay until launch. No card needed.


Most landlord apps are built to collect rent. Hundred Doors is built for investors who are still buying, and want to see exactly when the next door makes sense.
Rent and expenses
See who’s paid, who’s short and who’s late, and hand your CPA a Schedule E summary instead of a shoebox.

Loans and refinancing
Every balance, rate and maturity in one table, and what a cash-out refinance would free up on each property.

Your next deal
Run a deal both ways, bridge then refinance or a DSCR purchase, and see cash to close, cash left in, and when you can buy.

Rehabs and draws
Budget the scope, track what’s spent, and know which draw is next and what the lender needs to see first.

Lender schedule
Your schedule of real estate owned builds itself, one per LLC, as a PDF, a spreadsheet or a private link.

How it works
Set up in an evening.
01Add
Import your spreadsheet, or add each property in about a minute: address, rent, purchase price and loan.
02Fill in
Leases, loans, LLCs and rehabs. Add as much or as little as you like, and the rest of the app builds from it.
03Grow
Every Monday you get what’s coming up. Every time a lender asks, your schedule is ready. Every deal, you know the numbers.

Questions
Does it collect rent or screen tenants?
No. Hundred Doors tracks the rent you collect however you collect it now (Zelle, a payment app, your property manager) and tells you who’s paid. It’s built for running and growing the portfolio, not for being a payment processor.
Is my data safe?
Your data is stored in a secure database where each account can only ever see its own records, and it’s encrypted in transit. We never connect to your bank: bank import is a CSV file you choose to upload. You can download everything or delete your account at any time.
I have a property manager. Is this still for me?
Yes. Your property manager runs the day to day. Hundred Doors is where you see the whole picture across managers, LLCs and loans: equity, debt, balloons, refinance options and your next purchase.
Can I bring my existing spreadsheet?
Yes. Paste in the rows from Google Sheets or Excel and Hundred Doors maps the columns. You can also import transactions from your bank’s CSV export.
What if I only own one or two doors?
That’s the best time to start. Set it up while it’s small, and it grows with you, from your first door to your hundredth.
What happens at launch?
We’ll email you before anything changes. Founding members keep $19 a month for as long as they stay subscribed. If you decide it’s not for you, export your data and walk away. No contracts.
