I know you don't need pressure treated in the dry areas. 

I'm going into this endeavor like a dry sponge ready to absorb all information given to me..

When the REOs dried up, we were the first in our market (2011) to begin using direct mail and getting our portion of market share of motivated sellers who were not aware of the rising market. 

If the second unit does not have its own electric meter it should still work (worked for us,  we bought a home with attached apartment with our daughter who was a college student) also if the appraiser classifies the second unit as an accessory apartment or mother in law unit or casita instead of calling it a "duplex"   We're taking a gamble on a property right now where the underwriter said he believes the appraiser will be classify it as a single family with accessory unit (fingers crossed) this property is two separate homes with separate meters, so there's a chance appraiser will say the dreaded "duplex" and we wont qualify. 

Tip for DIYers: if there's no power in the house or you don't have a heat gun, use dry ice blocks and the vinyl tiles will come off very easy.

If you want some dry powder that's understandable.  

Even dry spaghetti noodles get thrown out if they've been opened.

I also "respect" the investor who didn't need to rehab, paint, drywall etc but just invested wisely and made his money while sipping a dry martini at an oceanside restaurant......

Keep your head down and your powder dry.

Baseboard hot water heaters are very efficient and provide a warm moist heat as opposed to dry heat.
