In additional to the interior commercial property there is also exterior commercial property available; including but bait limited to 2 large generators, a 20,000 gallon diesel tank, 25' light poles ect... 

I sadly know from experience that, even when pets are kept up-to-date with their flea medication, there can still be a flea problem.I'll even take your tenant at face value and look at it in the best possible light for her. 

Install outlets/switches/lights.

Just stay within your budget, keep it light and airy..don't over do it or over think it.. rule of thumb "KISS" keep is stupid simple.

Can you shed more light here . 

The particular situation I’m am in need of guidance on is a new tenant we have recently put in one of our homes and this person feels the need to text myself and my partner every time the house makes a noise or the air conditioner makes a sound they think is a problem or when the weather is bad and the lights blink......the list goes on and on.

@Garreton SmithHi Garreton,Walking distance services and stores the intended residents will like.Such as certain fast foods, liquor stores, grocery store, convenience stores, medical services, nothing too upscale/unaffordable.Good Lighting at night on the street vs. where the street lights get shot out by the local criminal element so they can sell drugs in darkness.Good Luck! 

I think we're still "a green light" here.

I have about 318 units in need of some light upgrading. 

Explain it in the nicest light possible and you might just get to keep one of them if they can handle the increase, but if it's a huge difference between current and market, then it's likely a good idea to get them out and do the work and remarket as a higher-class unit and try to find new people.
