Less than a mile from St.John Ascension hospital, quiet neighborhood, public transportation accessible and business accessible. 

I would suggest figuring out exactly where she wants to live, identifying the nearest transportation and working backwards from there.

. $2,925(included in my operations is a $50 per unit retained savings fee that I save in an account to help subsidize the cost of unit replacement scheduled @ 7 yrs.)My model works for me, however, the average cost per unit was $22,000 with transport and setup.

There is no pride of ownership and there may be external obselesce or factors like narrow one way roads, factories nearby, lack of access to public transportation and food. 

And to accommodate the cost of living based on the different city I am planning to look at the percentage contribution of the total income(Example: 40% rent, 20% food, 10% transportation etc) which should account for the cost of living

(I did not see a legally required time frame for a new lease or rent increase for unregulated apartments, please correct me if I'm wrong.)Would you require a security deposit with the new lease?

Having unregulated STR space in the city is just doesn't make sense even for common people.

I've focused some attention on land/home deals, parks, and starting a transportation business for the homes, and it occurs to me that yes these other businesses are services (and produce income) they don't help on such a micro level so to speak.

Impact fees in Montgomery county are 25,000 for schools and 13,000 for transportation, anything over about 5200 square feet is an extra 2 bucks a foot.

The trade, transportation and utilities industry added 4,200 jobs, a 2.1% improvement since June 2014.
