It sounds like what you are trying to do is to buy a home and get cash-back (in the form of an equity line of credit).

I'm pretty sure I would have a better return on my investment, and ultimately there would be nothing stopping me from going back to rentals if I chose to down the line.

I will pay to replace the lines and meter the lots, which will bring the expenses in line with a normal park, about 35%.

A lot of my units do not even get advertised because word of mouth usually has enough people looking for them and I have interested parties lined up by the time I have an empty unit

Maybe old utility lines that were taken out at some point and filled in.Could also be where an original termite treatment was done.

If you're in the same line of work you may still get a loan or working in your degreed major if getting out of school, otherwise changing jobs can be tough.

You may be safe here as I don't know the weather in Missouri (MS), but if it gets cold you'll want to make sure there is heat tape on the lines to protect from freezing.

My thoughts go along the lines that, if not satisfied, they would have started to foreclose.

Do you have difficulty in following certain steps that require analysis which may take you from one line of thinking initially to a different way of obtaining a goal?

I would look into your city and state codes, but in my experience when i installed a gas fireplace in my property instead of lining it with a new flue i simply installed a new b vent chimney inside the old brick one, and my water heater also was vented though the old brick as well with a 3" b vent, if you would like to bypass the old chimney all together and cap it (bug prevention) look into new 95% effecent furnaces, they are vented in PVC and can be vented out through side walls, they also make power vent water heaters if you did not want to convert to electric.
