I manage in Barstow Ca, I think the climate is similar to Arizona where you are, I install window swamp cooler, those guys cool up to 1200 square feet house very effectively n the power consumption is s no more than a typical appliance.

You are also working with less emotional clients and ones that are making more of a financial decision verses worrying about the color of the walls or what kind of flooring is in the living room.

If the lot is zoned RSA-5 (pretty typical residential zoning in Philadelphia) you should be able to build on 70% of the lot if it's a median lot and 80% if it's a corner lot.

I’m looking to get my house rented out by January 2019. How long does it normally take to find a good tenant?

The LLC would then pay U.S.A. taxes at the appropriate corporate rate (which the White House recently lowered).  

Typically I see tiny homes going for about $100.

Yes that is typical but with a 12 unit building you may be able to find a manager for less than 10%.

Don't fall for the idea that just because a property is in a white area, 3 houses outside of blue, it is safe.

We're in a coastal town, so the imagery and colors were chosen to reflect that as well.

There is typically one in Cornelius on the 3rd Wednesday of the month at Harvey's.
