I would never pay down existing mortgages I would just let them play out.  

Trying to figure out the “real” cost of installing a new central AC unit and replace existing old furnace.This is in San Jose, CAHome is 1600 sq ft - 2 story Got quotes that range from 8.5k to 15kI guess the need is a 3.5 ton compressor and a 2 stage energy efficient furnace.

It is because of you all that I still believe good people exist.

What has been your experience with a property with a Retainer Wall?

Of course the existing agreement is going to govern exactly how such a transfer would need to be handled but at a minimum the tenant would need to acquiesce in the transfer and terminate the option... likely by joining in execution of the deed.

I only caution everyone should remain vigilant and don't be willingly blind.In the world of criminology and fraud sometimes people change, they make a bad decision under pressures that didn't exist when you first met them. 

Are you looking to buy existing or develop ground up?
