Actually for you the best bet after those first two suggestions is the fairly new Western Mass REIA that is in Springfield.  

I bet I can locate a cashflowING property in Sac.  

If you buy in a market that doesn't cash flow, you're just placing a bet.  

BONUS: I bet you can meet a bunch of Realtors who specialize in distressed properties.

Because I am out of state, I am doing one showing next weekend and am betting this will generate at least one offer.

.($175*15) + ($300*11) = $5925 * 50 ~ $300k --> 45% vacancy by value --> $160kYou can go up, down and all around from there, but I'm willing to bet it'll be hard to go all the way up to $475k, even if the whole park is leased.

3) Would a conventional mortgage be the best bet? 

Your best bet to putting together a spread sheet you can use over and over is to get quotes from local contractors then make that your data base on a per square foot basis, unit basis or per linear foot.

Lots to consider and quite a steep learning curve for you, I'll bet.
