I'm back and here is my offer.
140k comps
70% 98k
insurance: $180 mth
taxes: $68 mth
REPAIRS: NOTICE IT IS IN ALL CAPS. BE CAREFUL.
I would estimate my repairs to be about 25k for this unit and for anything that might need to be touched up on the other unit while I am at it.
I would probably offer between $65k and $75k and let them counter me.
Is this a private owner or a bank. If it is private owner then I would do some sort of owner financing with some money down.
I know you are going to say it is in a good part of town and they are not NEGOTIATING, well how long has the property has been on the market. HOw long will it take to get the other side repaired and rented. My calculations about 30-90 days. See you always add in for unforseens everyone else is going to say NO, but I have been very SUCCESSFUL at the TIME AND CIRCUMSTANCES RULE and this is ALL I do for a LIVING so I must be doing something right. Let me know how it goes. Remember you are the one that is going to get stuck with ALL THE UNFORSEENS in the end so make it worth your while if they are not willing then MOVE TO ANOTHER DEAL.
