After you determined the property to be a good investment you will want to then calculate the Debt Service Coverage Ratio (DSCR).

Saving you about $150/month and you will still be mortgage debt free on or before your original schedule.

Details:$175k, 8 units, built 1966, $450 each unit rentassume 10% vacancy, 55% expenses, 4% interest rate, 25% down.Before raising the rents (basecase), I get 1.85% monthly rent to purchase price (2% rule)2.33 debt coverage ratio, 10 CAP, 21% cash on cash.All in all, not too bad.  

He owns a large portfolio of SFH and is completely debt free - that is his claim to fame.

My issue is that the duplex consistently rented and making money, but my maxed out credit cards are killing my debt to income ratio.

When looking at structuring a deal with or without debt, tax impacts will largely hinge on the amortization of loan costs and interest expense.

No loans, I could own them all debt free.I have my own workers for most of the work so fixing them up would cost me a lot less than hiring another contractor. 

My credit is currently tied up with student loan debt.
