Duplex Analysis

[Andrew L.]

I am looking at this duplex. Listing price is 128,500 and I was thinking of coming in at $117,500 with a max offer of $122,500. Rental income is 1,600 per month. Loan payment would be $672 per month at 6.25% with 25% down based on a 20 year ammo. Using the 50% rule it appears the numbers work at my max offer of $122,500. What do you gurus think?
