However, when I reached out to the husband he told me that they didn't feel comfortable having people come through because the wife is immunocompromised (weakened immune system).

While they disagree on whether there will be another major downtown in the short run, they all seem to agree, because of the large amount of liquidity (print money) from Feds, the dollar will be further weakened (inflation).

The only thing it does is weaken your negotiating position.I suspect that an attorney could use that to your advantage as there was no meeting of the minds, nor is there a contract in effect.One thing you might try is to send him a demand letter and have it served by a sheriff or constable, depending on how things are done in NC.  

Contingencies in general weaken contracts.

If you have a second and the deal goes bad, the HML's position is greately weakened.

Regardless of what you do many people will be sued in their lifetime for something whether it is valid or not.The best thing to do is be pro-active.Have a plan and run operations in a way that slant things in your favor if a case happens.When someone sues they tend to make many mistakes before it gets to court.Even if they have a valid or partially valid claim you can leverage their mistakes to weaken their position for a settlement before it goes to a judge.Money isn't the only thing lost in a suit.It's everyone's time to deal with it and money lost from not just the claim but focusing on money making activities as well.When an attorney sees an LLC or a corp versus an individual many will not take pro bono unless they have a slam dunk case.It will be more of a challenge with the extra layer of asset protection if you run it properly.You can create a master llc and then have a sub llc for each property etc.

Oil will soften Asphalt causing it to weaken and flow leading to ruts.

Personally, I see it as weakening the competition as most people will not overcome this hurdle and give up after a couple of deals.

Essentially, I don't want to be 100% invested in USD-based investments only to find either hyperinflation or some European-style major weakening of the dollar vis a vis the Chinese renminbi or something.

My concern though would be comingling - you can weaken the liability protection the multiple LLC's may give you.
