Be suspicious of replaced plastic  plumbing at the hot water heater and under sinks.

The single property building is most likely one water/sewer/gas/electric service.

After loan of the 52k, which we included mortgage, taxes, insurance, plus the water it looks like about a 20% cash flow about 150.00We did find a house hopefully ,still available, that if I can get for 30k when done will be able to get around appox. 28% and if I can get taxes reduced would be hopefully upwards of 35%.

If I were going to be cutting potential future buyers out based on type of financing they can use, that could shrink my pool of potential buyers, impact future value and marketability, and I'd want to know now.

So be sure that your contract has terms that you can actually meet, so that you don't end up in hot water with the owner.

Since this is not big enough to be seen as a commercial property, they'll be looking at sold comps and won't give you a mortgage on something that appears to be 'under water'.

Miles of bike paths, rentals, a water taxi, and many beaches to choose from.  

Formica counters looked to have a medium degree of water damage here and there. 

When using the Rental Calculator should I adjust my prices so that they reflect only one flow/unit of income and keep all my vacancy rates, cap ex, maintenance repairs, water, etc... all the same?
