Yet another thing also occurred to me while breaking down the numbers, the Selling cost after the repairs are done, specifically, the realtor commissions.

The Tenants agree not to permit any deterioration or destruction to occur while they are occupying the property. 19.ALTERATIONS:Tenant shall make no alterations, decorations, additions, or improvements in or to the premises without Landlords’ prior written consent, and then only by contractors or mechanics, or other approved by Landlord.

The appraiser explained appraised values had declined and I would be given a "quick sale" number (which was still 2X what I had paid for the house a decade earlier).The same type of appraisal inflation occurred during the real estate bubble of the 2000s leading up to the Financial Crisis of 2008 (The appraisal bubble: In run up to real estate bust, lenders pushed appraisers to inflate values).

I'm just worried about leveling the house which will require interior piers and exterior piers and other damage that might occur after the house is lifted/leveled... 

As in, the right occurs every time the property is about to change hands. 

A month can have varying degrees, like Houston or Florida, if a hurricane occurs.

An idea that occurred to me is the possibility of putting these 13 rentals into one bigloan and doing a cash out refi to cover a large part of the cost of our build, with the thought that the interest would then be deductible, which might have some tax benefits. 

Thank you Irina,The QCD was filed immediately after purchase, so all Cap Gains will have occured during the partnership.

If you want to keep it simple and easy I'd recommend WordPress for the site.

3rd home don't have much room to cash out compare to expense which will occurred to do this refinance.
