Yup open up the drywall for at least the first foot,  and test see how the insulation and drywall is in several spots.. you gotta get it figured out early because mold will start and once that sets in your talking issues.. 

Suggested the buyers replace ALL the insulation in the attic because he found a spot of mice droppings.

It's great that you are going to get the kitchen updated, that will expose some hiding spots.

It takes training, preparation, dedication, blood, sweet and tears.  

You will learn how to value property and in turn be able to spot bargains and opportunities.  

@Mark Poulton @Jeff Keller The floors are uneven in some spots.

You are spot on regarding the areas - the buildings in downtown just off base (76541) are going to be very tough, D class at best.

Ranch Penasquitos (PQ) and Rancho Bernardo (RB) are nice, but expensive spots on the I-15.

SO I am now assuming 21 spots total with no expansion.Expenses - He stated the $250 was lawn care, gravel maintenance when needed, and he also pays Roto Rooter to clean out the sewer lines every quarter as a courtesy, but this is actually not necessary since it is city maintained sewer.

He modified the terms on the spot, printed it and had us sign it right there.
