Hey Diandre, Less than 30% Down for a Commercial property is nearly impossible to find, unless you have other properties to cross-collateralize. 

I had 200 units go into contract about a month before the market's light switch was flipped, but that deal failed to close because the market had collapsed in the subsequent weeks and the buyer was unable to cross the finish line, so I still have that one.These last 1,000 units were all part of my last two multifamily funds, fund VI and VII.

I am looking to seller finance my rental home to a married couple, however i we are looking for reputable law firms/ attorneys in the bay area who have experience in Seller Financing transaction.

@Martin Yip Toll So You are making a mistake treating your debt relationships as strictly transactions.

That crosses geographic boundary lines so it's not reserved for out of the US.

look at your experience level with reality in mind.I would want to feel very comfortable about those things before spending time on deals and money when i had no real capacity to transact no matter who the lender was.
