My last two appraisals, I could not be there and got hit for stupid stuff and I had no chance to dispute it because once it's done you have no recourse against the appraiser or the appraisal.Big example, I got hit for a firebox within 6 inches of a flammable surface, both walls and the floor around the fireplace are solid concrete!!!

Would you install tile immediately following foundation repair or use a more flexible flooring surface (assume the area to be tiled was subject to the foundation repair)?

Just need to keep at it and the deals will surface.

There is so much here to read and think about, most likely will be a good while before I even scratch the surface.

One recommendation was to use a combination of plywood and sheet rock in place of the Cemesto, and then build the roof insulation and surface on top of this.The more I learn, this seems to be in the ballpark of $30-$40K for the new roof alone (not to mention the asbestos abatement which I've received estimates for at around $20K).I feel my only option would be to renegotiate with the seller, or as you say, be ready to walk away.  

I have laminate, cultured marble, corian/solid surface, and granite at various locations. 

@Jeff Kao Thank you for surfacing this great resource for me!

The city has very poor drainage so the farther away from the bayou and any of its tributaries, retention ponds or open ditches would be favorable.  

I think on the surface it looks like a great idea, but you should know the actual costs.

Thank you for the welcome @Michael Sato and @Brandon Turner appreciate it - I guess Brandon over time the help I may need will surface, but do appreciate the offer and I like the site.
