Can anyone recommend me a Private Flood Insurance Company?

Biggest issue to me would be water intrusion/mildew and the accompanying smell.

The two member condos were just formed to sell two dwellings on one lot and maybe share one water meter.

Simply bolted onto concrete flooring with no foundation perimeter to address water intrusion issues when it rains.

I am using most of the same numbers for all of this in my initial analysis as I want to be very conservative with my numbers. 10% for property management, a higher amount for insurance (depending if the property is in a flood zone I will add more) and maybe $150 in utilities that I would have to pay month to month.

All of them have a lifespan, Roofs, floors, hot water heater, appliances, hvac, bath and kitchen remodel, etc.

Questions:Have your tenants been okay with the staining and slight smells of this water?

You have to use money to give the seller "moving money", money to bring the loan current if they are behind, money for title reports, money for escrow, money for advertising, money for making the payments after you take ownership, money for repairs if needed, money for cleaning the property, money in reserve in case everything falls apart (just to mention the big ones, there are also Insurance, water, electricity, power, property taxes and so on).

Utilities in this area (-electric, water, sewer) are about $100 monthly if occupied. 

Do you know how to spot water damage?
