Security investigated to find the renters still at our house.

So a majority of the ownership groups would want to sell, plus since they are more sophisticated owners usually would sell through a broker to get max price and not sell privately.  

Since they are responsible for maintaining the relationship with you after the transaction closes, this approach adds an extra layer of confidence and security to your investment. 

My goal is to create financial security for retirement.

They are on a big push to get back in the game though, have you seen their recent ads stressing that they only list private homes?

Send me your site in private and I will evaluate it so everyone can learn from this, if that is OK with you?

Which one is more appealing - continuing to own the house or the security of that much cash/liquidity?

and the property had a private dwelling value appraisal much higher than the public property appraiser claims. 

IN these cases they took title sub to from the sellers .. ( but in the case your describing its the same thing you have a senior note as most investors will want security) they then sold on contract to buyers with small down payments and credit challenged or income challenged and they did about 30 of these in a year or so.. worked hard at it..

I also don't like the sardine effect where your just packed in a building, ocean lakes is tight with homes but still feels private at the house(s), golf cart community and 2 min from the ocean on a golf cart where ours are.
