I have built up some equity in a 1997 Double Wide investment that I rent.

Real estate investing clearly requires a wide range of skills to be successful.

Both driveways are about 11ft wide and 48 feet long .

This is not a wide-spread practice, but I think its worthwhile to research this and ensure yourself that you will not be stuck with the tenant's electric bill.

Markets are world wide, bugs spread

Bjorn - sorry I was not clear, I’m ok with him parking in the parking area, just not in the 5 ft wide yard beside the house.

When evaluating mobile home parks you would need to know about market value of current homes, are they single wide, double wide, is the park 100% full, are the utilities public or private, if private are they in good working order, what are market rents for homes in the area, what are rents for apartments, how much is the lot rent, how much are they paying in rent on each home for the 50% currently owned by the park, is it in a good market, are the rents being paid at market, are the lot rents at or below market, what are the real estate taxes, is there rent control, what capital improvements are needed for the park, etc...
