References and some due diligence into the marketing materials they provide you with.  

Recommend having the hole backfilled as needed with appropriate material.

But these properties won’t perform as advertised as you won’t collect anywhere near the projected or scheduled rent and expenses will be much higher than stated.There is an old saying: If it sounds too good to be true, it probably is.

@Timothy Bose, hey bud, be careful about any advertising except in Marketplace. 

While driving around at work and at jobs I will play BP Podcasts just to surround myself with the material. 

That website, and all the linked documents, are written like so many others whose operators are from outside the US (and have poor English language skills) and typically perpetuate loan scams on unsuspecting borrowers.Their “Terms & Conditions” document for the loan is a joke.And I can guarantee you that no real “private lender” is loaning money at what they’re advertising (i.e. $50k up to $800M @ 5% interest for 35 years).

Nor the expertise do the labor while paying 30-40k for materials. 

Then you advertise and your marketing system should deliver you highly qualified leads in line with your business goals. 

@Carlos Contreras if it is joint, I would look at rental ads in your area for apartments and see what they advertise.

I think there will be a lot of bargains next year, especially if you are good at creative dealmaking and can negotiate seller financing or "subject to" deals.Recently, I made an offer on a rental with a solid tenant and the numbers were good based on the advertised rent.
