For example, the poor performing stocks in my portfolio, I would dump the same year I sold real estate as this could offset capital gains from a real estate sale.  

You can buy performing notes for all the benefits of amortized payments w/o the hassles of termites, toilets, and tenants.

I'd recommend performing the escalation to the loan officer's manager, ask for someone who knows what they're doing, and see where that takes you.  

Then the banks will require details on the scope of work performed.

My advice is to stay away from commercial property until you understand how it's valued, and can perform a proper due diligence and valuation.    

You will be the new owner, but still perform a title search as there may be unforeseen additional issues.  

If the testing was performed by a home inspector, hopefully they are Registered Radon Testers with the State, and if so they are required to report it to DHHS on a monthly basis.  

What I would want to do in that situation would be take the performing asset to the local bank, get a 6% interest loan with a 15-20 year amortization, and then go to private money/HML for the rehab project, then refinance it when it's producing. 

As I am moving along in my education on RE I am starting to see a major need to track local market performance.

Pay to perform is the way it should be.
