I have 26k to play with on a cash out refinance. I am in the process of buying a duplex but I have some concerns. 75k is the current offer they gave me. I don't want to pay closing costs. The owners are paying for heat and water. Utilities are around 150 a month. Taxes 104 a month insurance is 77 a month. PM Fee is 8%. The rents are 900 total 450 per unit. I have to put 25% down because its going to be owned in a LLC. My interest on the loan will be 6%.
