Just debating to do it or not because I don't have any issues and don't want to pay $5 a month and have to constantly go check my mail at the post office. 

Some investors / flippers of very inexpensive vacant land do self-close, where the cost to close with a title company (most often requiring that you purchase title insurance, which comes with a minimum cost just for issuing a policy) approaches or exceeds the monetary value of the land. 

Buying as a primary allows you to put as little as 3.5% to 5% down.If you do have any issues with the business down the road you can always use a DSCR program which allows investors to buy an property without having to show income or employment.

any legal issues I should know about?

@Deonte Hill-  thanks ...trust your instinct ....yes - massive red flag . unless you have unlimited cash to  address  unlimited issues - be wary 

Shortly after I was advised by the utility company that there was an issue with my water that is indicating there is a massive leak.

I don't have much issue with this sort of thing.

Make sure there will be no issues renting the home.

It has been a collegiate rental for MANY years, and the current PM that showed it to me yesterday has been in charge of it since 2018 with no gaps in renters.This home is in fantastic shape....new services throughout, no exterior issues, nothing. 

Do you still speak to your coach should you have any issues that may arise with your existing portfolio?
