I think the home may go under contract today with a full price offer. 

It is normal to get cold feet but the main thing is to do the best due diligence you can do prior to going under contract-  "Pre-DD". 

You can do as little as 0% down and maybe even get money back at closing if you can implement seller credits into your offer during the inspection period or prior to going in contract. 

Unless you are running multiple business operations (like a PM business, sales, contracting) the need for a master LLC typically only creates havoc for you. 

I recently secured my first off-market property under contract.

Depending on your market, houses for sale, etc. they could cancel the contract and relist.

What we are really describing is “contract flipping”.  

:This is where the contract between (or at least having something in writing) would come in your favor.

This tax applies to rental contracts entered into on Jan 1 and after. 

If you have an accepted contract, the only thing I would really worry about is copies of all leases.If you are still underwriting and thinking of offering, the price is going to be more dictated based on your own knowledge and idea of what you can do with the property, versus what the seller financials state.
