They could rent out an investment property to a regular tenant but they wouldn't be guaranteed 100% vacancy and a responsible party to look after the property. 

Currently looking for CARPENTERS, ELECTRICIANS, PLUMBERS, ROOFERS, DEMOLITION MEN, WROUGHT IRON WELDERS, TUCK POINTING / SIDING, PAINTERS, GRANITE, CONCRETE, IN GROUND POOL PERSON, CLEANING/DETAILING PERSON, ROOFERS (regular and wood) and possibly some others I'm missing.  

@Brad Fausett Well, I think regular property inspections and getting a lawyer on the case as soon as issues emerged might have helped the situation.

This is an easy answer for me, since in a way, I start over on a regular basis.If I had nothing, and this includes no knowledge, I would start by:1 - learning: A - How money works, B - How to analyze markets (as in zipcodes), and how to then find Micro-Markets2 - Then, I would develop a plan of investing based on the two Core Knowledge Bases above.3 - Next, I find my money, as in cash partners and credit partners, all to be implemented on a project by project basis.4 - Now, I camp out in the market(s) I found in step 1, and invest following the plan I developed in Step 2

Nothing wrong with monitoring that, but it's not the 'metric' we quote as cash-on-cash.

I would have visited the apartment building more regularly and kept a list of which units were being repaired and re-rented.

Working with the PA DEP to set up monitoring programs for small system wells.

But it's a hassle to monitor so I pay now.They would get behind and the city would send me a letter to cut or they will bill me!

@Nathan Waters This sounds more like a syndication than a regular old JV that you could print off legal zoom.

You just use a regular lease,, list it by the room by number,, one person per room, one person per lease, if your renting by the room.
