Your lease language also plays a big role here and should explicitly spell out how/if that can be accepted. 

It is very important because after that date what you have ROW has to be spelled out like access only or utilities.

but for future reference, I spelled out early termination terms to my tenants before hand. 

Make sure everything is spelled out.

Canceling the contract without proper justification (those reasons should be spelled out in the contract) will get you sued for "specific performance" and/or "fraud in the inducement" and the seller may well look for consequential damages.Proper justification for canceling the contract is normally limited to home inspection and mortgage approval. 

A few years ago I helped my (retired) parents buy their most recent house by directly giving them a $100k cash down payment, and they would like to leave the house to me when they pass in thanks for the assistance (it ended up helping keep their mortgage extremely low since they are on a fixed income).They are very worried that it will somehow get caught up in probate or red tape when they pass even if my name is spelled out in the will, and wanted to see about just adding me to the title or something so that there is a seamless transition without any hassle.

@Dan Oxman as far as where in the code it says only capital gains are allowed:The benefits OZ's of sub section Z (1400Z-2) are spelled out under the 1400Z-2 heading "Special Rules for Capital Gains Invested IN Opportunity Zones" - this means that the OZ benefits ONLY apply to OZ investments funded with capital gains.Under 1400Z-2(e)(1) it spells out that any investment that consists of only a portion of gains will be broken out into two separate investments, with only the capital gain portion giving rise to any tax benefits.

This spells difficulty as either wages will increase, further pushing up cost of living for everyone or these businesses will have to close or move. in my humble opinion.

Just have a lawyer make a joint venture contract where the details are spelled out.

Have complementary skillsets and spell everything out in writing.
