I will be incorporating this into my leases. 

Now I am aware and we can move on, but seeing as this is the internet and first impressions are so strong my best bet at getting any further advice would probably be to go back to the drawing board, incorporate what I've learned and rephrase my questions. 

First, since mortgage interest and property taxes now have limited deductibility, would it make more sense to incorporate, even in a pass thru, to retain that deductibility? 

A good place to inquire would be the local government program manager (usually in Planning) for TDR.Now, you need to incorporate all this TDR information into the local market values.

That said, I think there is room for creative developers who incorporate elements like microhousing and co-housing and other quasi-shared living situations and who provide the types of amenities millennials want (gyms, dog washes, bocci ball, rooftop gardens, high speed internet, concierge, etc.).

If he used one of those... he is probably better off cutting his losses and expecting to not be able to use that bidding service again.That said... here's what I'd do.Step 1: Yell.Step 2: New title company.Step 3: Determine the terms of the existing 1st TD.Step 4: Determine if the terms of the existing 1st TD could in any way be supported by a tenant.Step 5: If Step 4 is a no go, approach the lender about a SS or DIL, incorporating into any agreement that the lender will not pursue a deficiency judgment.

Another thing I like about them when I was getting my first sites going was they had SimpleScripts incorporated right into the control panel.

I suppose that, given in which state the LLC is domiciled/incorporated, I'd have to file a state tax return for those states.

Even though I believe rates have peaked, and when they come down we will see another bull run in housing values, I think there is lots of uncertainty and people should make sure decisions work still when they incorporate downside risk into their underwriting.
