I have not bought anything from them, but I see their deals all the time.Most of them way over priced.I think their model is buy dirt cheap, sell  very high and convince people by offering 3 years rent guarantee. 

You have expertise in the negotiations and contract writing.

We know some people that are looking for rental (1-2 months) while they are finishing up their home re-modeling. 

I don't care for it, but it's part of their business model and you will be refunded less appraisal cost if they don't close. 

I believe I can use the hybrid model of using it for both STR and MTR.

Hoping you may also have experience with large language model as well.

Keep in mind, I am a professional appraiser and there have been two model match sales in my neighborhood in the last 6 months, so I know what my house is worth with a 2% variance. 

So while the proper expertise is vital in a successful ADU project... yes, please do question the tiny house start-up companies, or anyone touting themselves as "ADU experts" without the evidence to back that up.

Quote from @Chris Seveney: @Jay HinrichsYup and people will buy them at tax sale then sell them seller financed for $5k after paying $100 to some sucker who wants to own vacant unbuildable land in middle of no where for $100/month that model is a huge business bigger than most anyone can fathom frankly.

If anyone thinks they have the expertise to target pre-foreclosures in the face of federal laws, attorneys being in the mix dealing on either side of these matters, Realtors being aware of the legal environment, banks delaying procedures in anticipation of sales or solutions, bank employees reviewing contracts and pending steps, what a seller may do in expectation of a sale and other issues.......well, you just have at it.
