Dont forget if you are providing common area maintenance, if your paying parking lot lights or annual parking lot maintenance then they should be paying a portion of their share of that cost.

Here are expenses that I think about -Principle & interest-Taxes-Home insurance-Mortgage insurance (if you put less than 20% down)-Maintenance & repairs-Capital expenditures (Capex) -Vacancy -Utilities (some you'll pass off to your tenants 

The budget seems low on the new build. ( I'm not an expert).How did you find this deal? 

Eight days and your getting $1268 from Airbnb 😳.where are you renting to(area)and why are your rates so low, is this a hotel?

The interest on both loans is 10% which might be low if you are using hard money and high if you are using any other kind of loan.

Repairs and maintenance budget?

Share the highs, the lows, and the valuable lessons you’ve gathered along the way.

Also, I believe the LTR rate may not cover the costs including maintenance/repairs. 

if yes, go with subject to, no money down, only closing cost which minimal (no need title insurance). 2/ if you are in market to buy, look for creative finance deal (low entry point and lower interest than current market)reach out if need helps

Check the units periodically and schedule maintenance before things break or the tenants starts to complain.
