Can someone double-check my first deal?

[Justin Santiago]

Hello everyone! First time poster, long time watcher. I've used the calculations from the "Calculating Numbers on a Rental Property [Using The Four Square Method!]" BP Youtube video for this deal. Looks like a SOLID first time purchase, but this would be my first buy. Can someone look it over?

Finance is 20% down 30 year conventional loan. Here's by breakdown.

6 units / 800 = $4,800

Total Monthly Rental Income = $4,800

Tax = $320

Insurance = $60

Utilities = $350

Vacancy = $240

Repair = $600

Cap Ex = $600

Mortgage = $985

Property Manager = $480

Snow/Grass = $200

Total Monthly Expenses = $3835

Down Payment = 52,000

Closing = $8,000

Rehab = $15,000

Total Upfront Cost = 75,000

11,580 (Yearly Income) / 75,000 (Upfront Cost) = 15.44%
