You don't want to charge a price that someone would pay for a unit twice the size for example.With any property I have worked with to hold for rental income I always find it is easier to use an agent or PM for the area.  

Plan the space for standard size free standing appliances that can be easy changed out when necessary.In your drawing you mention "electrical box".... is that the location of the electrical panel (which would be costly to relocate) or is it an electrical outlet?

You can also see if there are obvious signs that a tank was abandoned (filled with sand or foam) in the past--like a fill or vent pipe (wide pipes going vertically up) near the basement outside, or a weird circular depression about the size of a tin can top in the concrete usually in front of the house.

I found a local place that will do similar font size and cover the same amount of windows for $150.00.

Is everything they pay in the intervening period rent  (i.e. there is no portion accumulated towards purchase)?

The credit pull number is an absolute formula.So while I think CF might work in certain situations, I don't see how it can work for any of the small to medium size investors out there. 

In most areas that system is sized not based on consumption but on the ability to deliver water to fight a fire.

@Kevin AllenIf you are talking about a multi-unit property (i.e. a 16-unit apartment) there is no expectation of privacy in the common areas of the property - including the grounds.If the property is a residential property (SFH, townhouse/duplex, etc) and you have not established in the lease that you would be retaining access to a portion of the property (garage, out-building, grounds) or that you would be providing an ongoing service (yard work, snow removal), it is reasonable for the tenant to expect quite enjoyment of the entire premises.  

I know which tenant caused the damage, as it was caused by their furniture rubbing back and forth in a certain spot.Each of the tenants gave me a portion of the security deposit.  

What sort of treatment procedure do you get for that price given the building size?
