I wouldn't be selling in this market personally, so if you don't sell the SFR and you really want to do this, a DSCR cash out refinance on the triplex, or a hard money 2nd is your only option to get the liquidity needed to make this move.

Our goal is to find and invest in cash-flowing properties.

Not really, as long as you are up front with a lender, most would just require you to show them the establishment of the LLC/accounts and then could proceed with that.

Probably their contract says they could do the same to you, just returning your earnest money as liquidated damages.Now if you were a cash buyer, that all might have different consequences.My 3rd thought is discuss this with your new employer. 

- Will your net worth growth from tax advantages, annual property appreciation, debt paydown, etc. be worth the upfront investment (i.e. down payment, closing costs, moving costs, renovation expenses, etc.)?

Benefits for my sister:- She gets into home ownership without any cash up front because I paid all the money down.- She starts building equity on her unit rather than renting.
