The salesman assures me that the vents are for air intake only and the unit can go flush - that if I open up the wall there will be sufficient air intake from the air between the studs - but of course he'd say that; he's trying to sell me the unit.Comments?

I had to buy space heaters for the other rooms.Two years later I was able to find a beautiful duplex in the same town that was much bigger, had a yard, a garage, and central forced air heat, for $1500.

This would total $1,600/mo.Other considerations:- Older septic system- Great set up for a shared laundry- Main house is in pretty nice condition as the owner had it as their primary residence and made several updates (gas forced air, cat5 cabling, hardwoods, etc.)- Requires property manager as I live ~1 hr away- Multiple income possibilities, but could mean more turnoverI was offering in the $220k range, or a higher price but with closing costs paid by seller to help minimize cash out of pocket. 

Cons are that it's not waterproof (so must stay indoors) and because you don't have the raw data, you can't control as many variables when creating time-lapse. 

Now that I've come up for air I figured it would be a good time to introduce myself and begin networking in order to take advantage of the other valuable resource BiggerPockets has to offer, the vast community full of like minded individuals with diverse skills, experience, and expertise.A little about myself...

Picking a "huge" number out of thin air is about accurate as throwing a dart at a board full of options while blindfolded.

@Kristine GarbergI was just in Italy for two weeks staying in various Air B & B's.

He may have mentioned Vegas because then you could use it as an Air BnB property.

Whether you air bnb, rent it out (seasonally or year-round), or just own it as a vacation home or part of a timeshare, I'd like to know how your numbers have changed and/or how you've had to adapt. 

Some initial thoughts:Does the house have central air?
