Is this market accessible for the average investor in the UK, or is it exclusively banks and hedge funds who buy/sell these sorts of instruments?

You also get the appreciation on the asset during the course of ownership, which is cash back to you at closing when you sell or refinance.

What are the gross yearly rents on sell outs?

This should eliminate the homeowner (1) selling a property while remaining liable for the note (subject to), (2) tying  up his property with a “buyer” who has no intent to close unless he finds someone to pay a higher price (wholesaler), (3) paying above market rental for an option to buy that can never be exercised (4) purchasing a property from a fix n flipper who did shoddy rehab, (5) purchasing a property with nebulous legal title, (6) contracting for home improvement with a fly by night contractor who then puts a mechanics lien on the property and (7) “listing” with a wholesaler disguised as a Realtor who doesn’t put the home on MLS. 

Buy it with 100% seller financing with a balloon note, buy it and close, thirty minutes later sell it and payoff the note.

I recently read that the City of San Jose will be the 1st to allow homeowners to sell their ADU separately from the primary.

Actually find out through that process that one of the tenants used their security deposit as rent one month.

Considering seller has no tax returns to show he may struggle to sell based off what he claims.

I paid the loan off in full earlier this year and am now under contract to sell, with the closing date upon us.

The selling realtor is telling me to put seller as the name of an individual (the individual and his wife are listed in the CAD contact address as a "trustees" but only as contact address, not as owner-the corp is the owner).
