@Yu Xiao, using that property as a short term rental during the time you own it will open up some additional tax saving potential as will doing a cost segregation study to take advantage of some accelerated depreciation.  

I also have a real estate lawyer in the Texas City area that will do transactions for a very reasonable price.

so - what are the ages of those items, how much will they cost to replace, and how long will they last? 

The negative is that the title ins can cost 3-4x or more than what traditional title ins will cost.
