So I've never had a blockage since doing this type of rehab.With 2 daughters I've pulled a lot of rats out of P-traps & their 2" shower drains P-traps at home & in their current homes.My days of climbing under vanities & kitchen sinks are over but then again I'm not as slim & agile as you.

In the driveway, with her car blocking them in, as if they were there before she got home (it's a long slim driveway).I don't see how it's "gun shy" to expect people to be screened and be on the lease, abiding by the terms of the lease they agreed to, that they may be in violation of.

I'd say with a SFD, slim and none. 

All 12 doors are currently rented, and the rental competition in this town of 3,000 is slim to none.Price = $700,000Taxes and Insurance = $2,000 per monthRental Income = $8,700 per monthIf purchased, I plan to pay down 20%...Would you consider this deal?

Where I am the chance of doing that is slim to none as houses are well over $200K. 

This is slim when compared to offerings of SFH.

I don´t think it will be a bloodbath, but there will be more opportunities than the slim pickings out there today.

Chances are pretty slim. 

All of those things cost money and should be accounted for in the initial equations or at the very least, a part of the monthly rents should be set aside to build up a reserve amount, but that would reduce the monthly "profit".Maybe this property will be all sunshine and lollipops and I hope it is, but I see lots of potential pitfalls and costs when margins are this slim.  

I would say it is in that difference (let's say, for example, you're only cash flowing $50-$100 per door, arguably a slim margin) that one can better assess the risk of life events (whether your own, the tenants', or a combination of both) and how they affect your investment(s) as a whole.Those numbers are based on actual properties...I didn't just pull them out of the air to make a point.
