One thought I've entertained, is possibly including something about if they recipient doesn't meet the profile, but are interested in still selling their property, that we are professional realtors and can assist them with that as well.

Our goal is to increase our net worth, to help supplement retirement income down the road and to currently provide a stream of cash flow to enjoy some of the finer things in life.We both work full time in professional careers and have so far found a way to manage careers and the real estate business while keeping up with two kids (15 yrs & 20 Yrs old).  

Remember this is a business and you need to keep it professional.

I don't know if you're aware but this building is under rent control and the 2nd unit's $1,900 rent cannot be raised much and there are tight restrictions on removing the tenant.The type of buyers this property is perfect for are two separate parties (think friends or siblings) buying it as a TIC with each party occupying one unit.  

It is the prime and hot area for young professionals.

She found a new professional job before we applied for the mortgage, but Wells Fargo would only count my salary when they were figuring out our debt : income ratio because she had not been "continuously employed for the past 6 months".

Very doubtful in our situation.Can anyone suggest a creative buying strategy that might satisfy all parties?

I am a principal party in a valid and assignable Purchase and Sales Agreement which allows me to purchase 123 ABC St.

You need a signed cancellation from both parties, and then the selling brokerage has to release the funds.
