From what I have read, however, competition for MF is getting pretty heated, so I guess you'll have to check your local market.We started with SF and that was nice because we could kind of gauge the maintenance, repairs, and capex expenditures from the beginning. 

On the other hand, if the area is known for mold and moisture due to the proximity of the ocean, and the house didn't have mold when the tenant moved in, and nothing is leaking (i.e. from another unit) and the heating/cooling system works, I would imagine it's either mother nature or the tenant that is causing the mold now.

I found Arizona Mission Heating & Cooling – (520)822-8499, hopefully this looks right. 

Is it finished space with heating/cooling and normal ceiling height? 

You could even use the oven for storage (not joking) if cabinet space is at a premium.KnutePro tip: Only store things in the oven that can tolerate high heat.

I stumbled across a website that had heat maps and rankings for the cities in terms of most desireable so I was just looking to see if some of those would be confirmed by a local as being correct.

I’m zero’ing in on zip codes and neighborhoods that were the hottest over the past 2 years and I’ve been checking daily on just these areas with somewhat of blinders to the rest.Again, we are in triple digit heat, maybe ppls just don’t wanna venture out as much...

So we upgraded the living room carpets & then redid the kitchen with my daughters old cabinets & immediately got $775/month.we inherited two older women who paid $425/month so we got them a new stove that worked, a new gas dryer that actually worked & then because of their high heating bills we upgraded the furnace, threw in a couple of gallons of paint so they could paint the kitchen & bathroom. 

I don't know what the electric cost is to run them but you are giving your tenants heat and AC which they will like.

One of the advice I would give you if you do start thinking about investing here is don't buy properties that use oil to heat water or heat the property, it gets expensive quickly.
