Feedback on first potential deal

[Steve Hilborn]

I'm looking at a duplex that's in a small town (700 pop) about 30 min away from major civilizations.  Seems to be made up of commuters and small town type people.  The building is 100 years old, but the owner's almost completely rehabed it and then apparently ran out of money and are getting a divorce.  I don't know the rental market in the area that well, but I put an add on CL for $800 and received 9 responses in 3 days.  So here are my rough numbers.

Purchase Price 90K

Finish rehab est. 10K

ARV 130K

Taxes                     900

Ins  est                   600

W/S/G  est             1000

Rents est              1600-1700

Questions:

1  what should I estimate for repairs/cap ex on a rehabed 100 year old duplex?

2  how concerned should I be that I don't know the town very well and it's so small?

3  how do the numbers look?

Thanks in advance for your input
