Advice for our family home. We're stuck & need creative solution!

[Drew Hoffos]

Hi friends! Wife and I own restaurants. Two investment properties out of town.
Sold our family home during the pandemic due to our third child and now we're stuck living with my in-laws.
(yes, the built-in babysitter is nice... but we need our own space for God's sake!)

The rates on our investments are too low to cash out refi. (26 years left on the notes). Don't want to take capital gains on them either.
Due to the pandemic our tax returns look tragic the past two years (thanks to our creative accountant).
Stated income mortgages in the 8%'s?!
We're a family of 5, so need at LEAST a 3 bedroom in a B - A- neighborhood.
Nothing in San Diego can be had under a million for what we need/want. And while we potentially could afford up to an $8000 payment, we can't get qualified.
Ok, finally getting to the question here....
*** Does anyone have any creative solution for a problem like this? I'm assuming a cosigner would be the easiest, but our parents are both leveraged out too far for their fixed incomes to qualify for the $8k debt to income situation.

Lease to buy? Has that ever worked for anyone? 
Local billionaire's adopting 41 year old chefs? 

Sincerely appreciate any advice! Stay well friends.
