I'd suggest researching the different types of investing methods and then choosing one that interests you the most and mastering it.

I dunno man - it's lazy advice and only hits one method of investing.

The only concern  I have with conventional is I have to put them in my personal name and debt to income.

I plan to use the BRRR method on this and just found out the house next door is for sale and might be next in line.

My wife and I worked to mitigate the water troubles as best we could and actually that is not my greatest concern.

NOTE: This does not mean what they think they can get for the property financed by anyone...... it's what they think they can get for the property.... it may require waiting on the right buyer)So each method is different and each has a different purpose.

Any concerns about foundational issues with the burrowing under the house? 

First off, I agree with @Brandon Hall, it should be the BARRR method! 

One of the complaints I have often heard is that most real estate agents are only concerned about retail buying and selling customers who will probably only have three real estate transactions in their lifetime.

I would be more concerned if they had only one landlord reference...
