@Gary F. it really depends on the location of the property and what buyers are doing in the area. 

According to the realtor, this transaction has been approved by the hard money lender and title company already.I have set a firm price at $100k, which is a good deal for the buyer, but I'd like the quick sale.Here comes the sketchy part: They would like me to accept payment of $125k with $25k being commission for the realtor, which the realtor is then going to use to pay the down payment. 

For the Average buyer this would have been disaster.. we simply built a new construction on it and did OK.. but this full blown rehab can be a real challenge for many .. its one thing to replace kitchen baths paint carpet roof.but when it comes to structural or these really old houses you get from Charleston north into New England.. etc its far more complicated and risky.

How do you qualify your buyers?

Plus, there's a decent chance the buyer of your property would allow a delayed closing in order for you to better "identify" your next purchase. 

Plans are submitted to city, will start on "in-place" type reno next week for existing bath.Goal would be to find a buyer early so that we can either sell as soon as it is complete, or even sell it now - bonus for buyer would be they can customize a bit if desired (e.g. here are your two choices we include in this price range. or pay more to get whatever custom version you want). 

Do you know any good buyer’s agent and local lender there?

From my understanding though, with land contracts, most buyers put hardly any money down. 

It may be the type of rental that is turning buyers off. 

He'd accepted an offer of $120k before the other buyer pulled out.Link to Zillow ListingI know he's had quotes of $30k-$50k to put a new roof on and repair some structural damage due to neglect.
