Now, if anyone offers me loan (or) upfront fee, I would ask to go through "Escrow".

I'm in Minnesota and Farmer's Insurance offers pontoon coverage for a rental. 

I wonder what investors offer as a means not to have the sellers pay the gain all at once. etc. 

It's all about what you have to offer.

Harvest Blue Houston, a registered series of Texas Real Estate Group LLCTexas is one of the few states that offer series LLC.

@Jared Schottthe short answer is - if the house is already on the market, it's extremely unlikely that they will accept a seller finance offer. 

The folks at mass save said there is a new program as of 2023 that offers $5000 per unit for knob and tube remediation and said I could take a heat loan of max $10,000 per unit as well for the balance so I am hoping that is true.

Of course they can get a higher sale price if they are willing to take on someone who cannot get a loan, or are offering better terms than current loan options.

It's a bridge that creates opportunities to get creative or to make cash offers on RE.

Or just put an offer into it?
