I am curious to know if when you say "Drainage system" does that include perimeter drain around the garage?

The house is a 4/1 1930's bungalow in the metro Atlanta area located in a popular/heavily hipster populated part of town (inside the perimeter off the proposed belt line, for those familiar with the area).  

The foundation perimeter is divided into segments, usually three or four feet long that will be labeled something like A, B, C, D, E. and then repeated.

We use them as perimeter alarms at our construction sites near our equipment too for would-be thieves trying to walk off with materials or the big yellow iron. 

I'd tape off the trim and brush the perimeter with a large brush and then roll the rest.  

Hello,I am looking at a 1985 single-wide MH 14'x72' on a perimeter brick wall foundation in a deeded lot MH subdivision (real property).

So I would start by doing the above find market rental rates and lease terms, then apply a vacancy rate that is within market perimeters (at least one months rent 8%), find the R.E. taxes from the assessors offices, add your insurance expense that they quoted you, now in terms of the variable expenses that would depend on your lease structure. 

I wouldn't recommend it for a rental home in my area - unless that was a common feature in the market I was renting in.In general, in my area, unless the house has a basement with a perimeter drain that drains to daylight or has a very low water table, it seems likely to me that the basement will "flood" at some point. 

@Randall Prosisehttps://www.scottsdaleaz.gov/codes/swimming-poolsScottsdale’s current swimming pool barrier requirements apply to all single-family residential swimming pools, spas and hot tubs constructed after July 20, 1995.Since the requirements are not retroactive, pools constructed prior to July 15, 1992, need only comply with the 54” perimeter yard fencing and gate requirement in effect at the time.

I have seen one that ran the entire perimeter of the lot, with T's that would have been for faucets at various points that went all the way to the road (Maybe model T's needed a lot of water?
