lol.Need advise on how to gauge their motivation to sell if they won't even provide a phone number for some live interaction. 

I'm wondering if I should sell the property now (probably what HOA is trying to pressure me into), try and get formal approval from the HOA to turn my unit into a rental (which is apparently really difficult to do now), or sell the property once the current tenant decides to leave?  

An encapsulate isn't a paint, it's a special coating that has to be applied to a specific thickness using a special gauge only after a specific test is done to the surface to be encapsulated to be sure the paint is sticking well enough to the wood to be encapsulated.

There is absolutely zero pressure for me to represent buyers and sellers as an agent, though, which was important to me.

This will help you gauge his motivation a little more. 

I was lucky to have a wife that has been saving for about 25 years so I don't have a lot of pressure on me.  

For a long time I was always pressuring them," When are you going to accept nonaccredited investors".

Those requests continue because they are demanding people and because you already demonstrated you cave in to pressure.  

Usually we'll replace old galvanized plumbing, especially if there's low water pressure.

We just wanted to get a gauge of what has worked for other investors.
