I've recently learned more about real estate investing and figured I had a good foundation of knowledge.

The first I would suggest is Brandon Turner's Book on Rental Property Investing and second, I would read his Book on Investing with No or Little Money Down - this will cater directly to your need but first you want the foundation of his 1st book and a little more knowledge (experience) in the REI community.

I don't see any foundation issues and only a few minor vertical cracks on the main floor.

Duc-Dung Pham for foundation work you want to speak to Vince Powell at Foundation Doctor in Harrisburg NC.

I've found that's the best way to keep the lookey-loos away and the rent payments late.As they drive off, rub your belly-button all deliverance-like.

Know what to spot in foundations. 

Not all companies provide the NCOA (National Change of Address) or CASS (address standardization for deliverability) certificates.By working with a list company that utilizes these processes, you can save on postage for the bulk permits.

I'm worried about damage to foundation.

The lot is .50 acres, with a very small house that needs some work, along with the foundation.

That is basically one of the foundational upsides of rental property investing- have someone else pay and build equity for you.
