This is a solid buy. Your ROI is rather awesome honestly. Even better at 165k. I'd start even lower :)
Here are the numbers as I see them at 180k price tag.
% Down Payment 3.50%
Down Payment $6,300
Remainder of closing costs $5,500.00
Total Due at Signing $11,800
Mortgage Rate 4.25%
Length of Mortgage in years 30
Monthly Mortgage payment $854.50
Taxes $300.00 (made up, but PITI is $1254 total)
Sewer and Water $133.33 (in most MFH the owner pays ALL of this expense)
Trash $- (is this included in your taxes? I.e. City trash? If not, plan on another $100/month. This kills the deal.)
Heat/Utilities $- (only shared utilities: porch/cellar/hallway lights)
HOA $-
Cap Ex and Ops $200.00 (given the comments on the roof and HVAC, save AT LEAST this much)
Insurance $100.00 (made up, but PITI is $1254 total)
Mgmt Fee $172.50 (figure this in now. If you don't you will handcuff yourself to a bad deal down the road. Even if you self manage, pay this amount OUT of the property's account each month so you get used to accounting for it. Given what you've said, I'd put it in your personal account for some piece of mind)
Vacancy $139.73 (8.1% represents 1 vacancy per unit per year)
Total Expenses $1,900.06
Unit 1 $575.00
Unit 2 $575.00
Unit 3 $575.00
Unit 4 $- (this is you. Later this will be another rented apartment)
Total Revenue $1,725.00
Cashflow/month $(175.06) This is your portion of the costs to bear. You were paying $750, now you are paying $176. Win for you.
