Then ask a contractor to take a look and give you a ball-park. 

They got one low-ball offer right before ours so we came in at 235/240.

@Ann NguyenIt really depends on where they are dropping the ball.

I would be careful about just sending out low ball offers to just see if they fly. 

Anywhere in the ball park would work for you.

Sorry if it’s such an odd ball post or something that’s been answered before.

Obtain your financing in your name not the LLC3.Quick claim deed it back to the LLCBased on the rule from my previous reply this is allowed and the bank can not exercise the right to call the note on the transfer.Option BObtain Commercial financing in the name of the LLC and close it in the LLC which will not have as favorable terms as the Residential loan. 

Time to exercise what we've been up to now only been learning/hearing about...We are preparing for a second conversation with this seller, and to present numbers. 

I already made a low ball cash offer on this same property earlier this year and it was rejected (property is priced way above market in a fixer upper condition).A subsequent offer by another buyer fell through due to bank financing (predictable).

By the end of those 3 you should be very knowledgable and should be able to get the ball rolling at least!
