Anything can be fixed however if the underlying problem is the soil then you will continue to have possible problems. 

And yeah, one or two experienced guys and, gasp, lawyers representing the banks, helped me out because they saw I wasn't playing around or wasting their time.You're here and you're asking questions.

I handled maintenance.When January arrived, we bought it and I just continued doing what I had been doing for six months.

I don't know that specific market but I can tell you this: the costs are significantly down-played by most owners of vacation rentals.

I intend to continue building "the company," not build a law practice. 

I have some capital that I would like to invest and I am wondering if I should buy my own home or continue renting and invest it in a rental.

We have to install filtration equipment when redeveloping a property, but not when purchasing to continue an existing use.

My Plan is to continue my day job and in my spare time learn more about how to partner with other investors to tackle our own development project.

How does this play into my home purchase?

If the property you're buying is owner occupied, the investor concentration doesn't come into play because you will improve the investor concentration.
