@Bruce Kozak I do not do this personally, but know someone who charges a fee of $12.50 per adult for water, with a provision in the lease that says any leaks reasonably observable by the tenant must be reported within 1 day or there will be a charge for the additional water use from that month's bill.

of deals later, I can offer one observation: you'll never do deals until you start talking to people. 

@Robert Leonard   just a casual observation is all. 

Unfortunately, it is very hard to understand a large vast city like Philadelphia without first hand knowledge so some of your observations are common misunderstandings.First, 2642 Lehigh is indeed a real address (if interested you may speak to the owner we manage the property for) but being .5 miles from Temple university it is NOT close.  

I'm familiar with the idea of visiting a property and getting a 'feel' for the neighborhood types, but how can you back that up with hard data, or at the very least, concrete observations?

This all comes from observations I have seen in my small city.  

Edited, while I was on my rant, Bryan made some great observations, I'd not say you can take on an investor so much as he pointed out, but not far from my opinion.

If you can take a property sub2 without persoanlly signing any promises to pay and the ONLY recourse is to take the property itself back, you are fine and in the clear as far as I can see (I am not an attorney and this is just by opinion adn observation, do not construe this with legal advice and consult with your attorney on it before moving forward) Age related restrictions?

If you're not familiar with the life cycle of a probate case it may be worthwhile to go to your local probate court anyway just to observe and look at a few case files.

Not sure what the condition is like these days, but that was my observation of a military town.
