Looking at urban infill where people want to live, where the jobs are, where transportation costs are lower etc. is a better and more practical solution IMO. 

But our back yard is not enclosed and joins other property as the tennis courts are behind our townhouse.

If one want's a safer place to play in that arena I'd suggest to follow the Oracle of Omaha and look into the transportation leg of O&G, more volume = more transport = more revenue = more profits.  100% correct, but wasn't expecting someone on an REI forum to come at energy like this.

Many PadSplit residents rely on public transportation, so being close to bus stops, transits, and other forms of public transport is vital when identifying deals, at least here in Atlanta. 

Interest rate 7.5%Property details: 4 Bed, 2 Bath, fully enclosed pool, 2195 sq ft living area (planning to have at least 14 guests)Anticipated revenue: 5k/month (this is conservative end)Total Expenses/month: 3.9k (mortgage + taxes + insurance = 2.8k/month)Cash on Cash return: 9%The issue we found on our original numbers vs what is coming back now from the mortgage lender is that the insurance is MUCH higher than anticipated (77/month flood and approx 360/month property).

It impacts the cost of everything...food, shelter, transportation, health, recreation, labor. 

Those aren't going anywhere so there's a strong economic base but also looking at the city logistically it has all forms of transportation with a high volume of traffic coming through.

Permitting costs can be reduced for facilities with multiple buildings ongoing as they can negotiate discounts and use a third party to permit that is certified by the state.Now, you do need to transport the home, but here distance is a factor, sure if you are going to ship 100's of miles this can add up but in general there is a service area for delivery at nominal cost.Those designs over 1 story will cost more as you need to rent a crane but that is another area you can manage cost.In the end I am pushing back against a blanket statement that "modulars cost as much and are built to poor quality" because frankly that is wrong.

@Mindy Jensen Is there a shuttle or transportation from the Gaylord Opryland to the off-site Sunday night happy hour/welcome event?  

I don't have the best means for transportation at the moment to attend physical meets.
