I don’t think they put on the contract that their duty is to find you the most competitive price so don’t see a high likelihood of the contract being void and releasing you from whatever you signed.

You guys might be a little quick on the trigger here;  in many, if not most, jurisdictions an owner can pull permits/function as a GC Only on an owner occupied property, not as an investor/flipper, and usually requires the owner to retain the home for at least a year before selling/renting, to qualify for that exemption.While the OP may indeed need a new accountant, he doesn't even know what kind of license the accountant was referring to, apparently he didn't even ask.

@Joshua Horn that will depend on how your contract is worded.

I recently placed a condo here in Omaha, Nebraska under contract and I am looking to get some quotes.

How often does this trigger the due on sale clause?

For the current condo like @Clayton Mobley said, you need to purchase at least as much as your net sale (contract price minus closing costs or around $300K in this case) and you need to use all of the proceeds from the sale (the net sales price minus mortgage payoff or $175K in this case) in your replacement purchases - if you want to avoid all tax. 

Current tax basis is approximately 25%-35% of FMV and the sale would trigger a sizable capital gain. 

Separately, got a house under contract in a solid neighborhood of Kenosha this week, continuing to invest in the area.

I’ve been asked a few times to do a joint venture with other local investors who wholesale and wanted to know if a specific JV contract is needed.

Just got my first single family rental property under contract and am looking for recommendations of good lenders in the greater Houston area.
