This is all public data, except for the rentometer estimated rents (which you should expect to mark up for being fully-furnished). 

maybe only be extra $40,000 to build open loft... and I would guess I could possibly charge $2000/mo rent, not sure>>***I was kinda crunching numbers...if I'm estimating it correctly it will take me over 4.5 to 6.5 years in excess rent to make up the cost of building the private loft.....does that seem worth the extra loft cost?

I'd love to get some more info about approximate rates that we would be dealing with :)

I’ll add that we were already charged approximately $90 for the initial microwave diagnosis service call separately.

The Math:Purchase Price: Between $850000 - $900,000 (As-is value is approximately $1.1M listing)Current Mobile Home Rents Avg. $700/month (about 35% below market, which is closer to $1,000-$1,200) or approximately $6300 per month.Multifamily Property is Currently vacant, but there’s a signed letter of intent from a state housing agency to lease the property on a 5-year NNN lease at $3,000/month.This property has stable cash flow now, with a strong potential for upside by adjusting the mobile home rents to market rate.

I'm originally from Western PA as well (Slippery Rock) and now reside in Atlanta.Here is how I am looking at it along with the assumptions I am making:1) I think the growth prospects are better in the Atlanta market than Pittsburgh from a pure demographics standpoint.2) I estimate your return on equity at 7.2% currently3) Over the long haul appreciation is going to take you further when it comes to net worth than cashflow will4) Doubling of the roofs is doubling the expensesThings to consider:1) What is the year built of your Atlanta property vs. what you could replace it with in PGH?

All I can say is I’ve seen it time and time again, accuracy in your estimates, detail in your work, and anticipating future costs/market changes and building contingencies in your budgets may cost you some deals but will save your investments. 

Much more negative when including realistic expense estimates (maintenance/cap ex, vacancy, PM, misc).  

Quote from @Michael Belz: Now, I have two options: I could fix and flip it with an estimated $200K rehab for an ARV (After Repair Value) of $825K, having purchased it for $465K. 

@Vikash NandConsider books like “The Book on Estimating Rehab Costs” by J.
