@Dennis DoughertyI’d sell it and invest your money into a cash flowing property.

Would experienced investors stick it out or minimize losses by selling?

A seller down in the Gallatin Valley these days wouldn't really offer seller financing, unless the lot was hard to sell, as people from out of state are just buying up everything with cash right now.

If I was a wholesaler and was selling as is, I would be wary of investors who tried to talk down the price after coming to terms.

The other thing to consider is the original owner has died, leaving the estate to his sister and nephew to sell.

I'm a realtor here in Missoula, and I'm planning a large subdivision project with a partner of mine in nearby town, we'd be selling roughly 200 homes.

I have helped a few different clients build homes and then sell them or build to rent/keep them and it can be a really fun and exciting process if done correctly!

You could have the seller add you to title before the sale (you'd want an airtight contract), and then fund just the rehab in cash, sell the property and split the proceeds with the seller upon sale/exit. 

I was considering selling a property using a land contract or contract for deed.

but if you're not in such a position, you're not.I thought about house hacking, but where we are does not seem like my wife would want to move again and then we would have to sell.
