That could be a fair compromise between the current unlimited availability of tax deferment (including the possibility to complete avoidance via step up basis upon death)*, and eliminating it entirely (as the Trump tax cuts did to exchanges of al non-real estate property).  

I’m willing to compromise the distance from work since I only report a weekend a month to my unit.

@Dan PowersI am seeing some compromise on the numbers or expectations to avoid taxes.

For example, if I wanted to refi into a conventional loan after taking the Heloc, would my equity be compromised I have to pay PMI?

However, I wouldn't compromise that contingency if I need financing.

It’s the “compromise” between owner’s rights and protecting your neighbors from living next to a hotel which zoning wouldn’t allow to be built.

One thing I will say is establish your criteria, don't compromise and do not give up.

In my mind i didnt like it at first since i just spent money on the landscaping but in the end we compromised.

Perhaps if you're comfortable with him being there, compromise with a month-to-month lease for him.

Now if you were unaware of this, and you could prove the seller knew there was structural damage, thats another story, But just because something has damage, doesnt necessarily mean the structure is compromised, and the sell may have thought it was fine.
