Austria, Germany, Luxembourg; these immediately come to mind as "ancient" developed areas in contrast to the "infant" that is USA, and they seem to be doing very well, very efficient, very well setup and established across the strata's. 

If the house is under water with the OCWEN mortgage, then approach the mortgage holder about a short sale. 

@Edreco AmosMiami’s market can be tricky for cash flow since condo fees and insurance costs can eat into your profits, especially with newer buildings or those near the water.

We have had duplexes with shared water, sewer, and trash billing, as well as shared driveways.The long term tenants act more like owner occupants, planting flowers, etc. and in some cases neighbors think that they are the owners. 

so i'll throw out my standard cold water.

It covers internet, water, trash, cable, and exterior (roof, siding, etc.).

Primarily desert washes, but also near a creek....So I would go knock on doors and ask neighbors when it has flooded and what they think about the area......maybe call the County water board and ask then what has happened there in the past.

Sewer and water in my area is around 10k a unit.

Water galore.

As for the first, yes we'd be able to do that (for example, replacing a water heater which is the mechanical that's closest to the end of its useful life).
