We do TONS of fix and flips here in Denver, and I help numerous STR clients as well.

They are there to knock out the scope and mitigate risk amongst numerous contractors. 

It also appears that there are numerous companies / doctors / therapist that will provide whatever documentation you want for a fee, so even If I did get this documentation I'd have to vet if it actually means anything.

We would love to buy a property in Boca Raton, I know there are strict regulations when it comes to STR, does anyone have experience with it? 

They have wants and desires, and presumably among those wants and desires is: not crushing the dreams of home buyers, getting additional business from lenders and sellers, doing the right thing in the face of ridiculous government regulation, etc.Perhaps you are able to complete your job with zero emotion (unlikely, even though you may think you do), but most of the rest of the world can't, even if they might want to.As a smart investor and business-person, I take advantage of this when possible.

Larger multi families (3-5 units) aren’t as numerous, but they still exist and can be great opportunities if numbers make sense for you.

Sale Price compared to List Price has quickly regulated up to no noticeable difference between what a property is listed for and eventually selling for on average.

While seller financing offers numerous advantages, including tax benefits and continued income for heirs, it seems he's set on selling for cash.

- Do any of you have an str in a multi family, what are the regulations on that?

Are there any building regulations for quadplex that are more complicated compared to duplexes?
