Repairs were $25,000.

we have had a bit of a roadblock since the duplex are listed in the city as two single family homes. we have had evaluations done before and they are worth twice as much after the repairs. do you guys work with credit of 640?  

Even if you do find such a deal, getting it to cash flow after repairs and a cash-out refinance is extremely difficult, especially for single-family homes.

Other than the repairs needed of course

I recommend you budget 5% of the gross rent (for the whole place, even what the rent would be if you were living in it as a tenant) for repairs and 5% for capital expenditures.

They obviously cannot control some costs, but they do have input on things like maintenance and repairs and some other things.

Others focus on achieving a profit of at least 10%-15% of the ARV (After Repair Value).

In any case, successful wholesaling REQUIRES the knowledge, experience, and ability to accurately estimate repair and rehab costs and time.  

Handle a few properties for other owners, minor repairs, find new tenants, and rake in 10% .

Current owner is willing to break even on the purchase price however, in my opinion I think he should consider 5 or 10k less then the purchase price considering the amount of repairs he neglected over the length of ownership.
