Sound familiar?
Rent comes in. Bills go out. Which door is paying you?
It lands on the first of the month, and you can’t tell which door is carrying the others.
You know what you paid and what it appraised for, but not how much of your cash is still in the deal.
You sort the year by property over a weekend, and your CPA still has questions.
A full sample year
See a finished year before you start yours.
The kit comes with a complete sample year for Maple Street Rentals: a duplex, a single-family house and a BRRRR on Birch Ave bought in February. Three properties, four doors, twelve months of rent, repairs, loans and a refinance, already filled in.
Click around, see what every tab does, then open the blank tracker and do the same with your own properties.
Maple Street Rentals is fictional. The numbers are a worked example, not a promise of results.

BRRRR & Refinance
Did the refinance get your money back?
The BRRRR & Refinance tab follows up to five deals at a time: purchase, rehab and holding costs, the 70% rule, the refinance, the cash you got back and what’s still in the deal.
In the sample, Birch Ave went 7% over its rehab budget and past the 70% rule. The refinance still returned 87% of the cash, and the rent covers the new loan with $237 a month to spare.
The tab flags the rule-of-thumb checks. It doesn’t replace your lender’s numbers or your CPA.

Is it right for you?
Built for long-term rentals, on purpose.
A good fit if you
- Own up to 10 long-term rentals: houses, duplexes or small multifamily
- Report your rentals on Schedule E, on your own or through a single-member LLC
- Use BRRRR, or want to try it on your next deal
- Want cash flow per door without learning accounting software
Probably not a fit if you
- Rent by the night on Airbnb or Vrbo (that’s the STR Kit)
- Buy houses to sell, not to hold (that’s the Fix-and-Flip Kit)
- Own commercial property or a portfolio held in a partnership
- Would rather hand the books to someone else
Rent by the night too? See the STR Kit. Flip houses? See the Fix-and-Flip Kit. Want it done for you? See landlord bookkeeping or book a free Discovery Call.

Landlords ask me the same three questions: which door is really making money, who hasn’t paid, and did the refinance work. This kit answers all three, using the same tracking I use with my monthly bookkeeping clients.
