Here are three things commercial agents need to do:1) Build a good Rolodex2) Learn the math3) Understand buildings and the features that are important to clients: electrical amperage and phases, ada compliance, connectivity, buildout options, parking, HVAC capacity and air exchange rates, fire suppression systems… 

Investors who want to learn a new business; who want to read and understand ADA law as it applies to innkeepers; who want think of new ways to attract guests, and enhance stays; who actively learn how to recognize and take precautious against high risk guests; and who learn how to do all this without refunding gusts left and right . . . those investors will always find opportunies.

I was sold a unit that ended up being ADA compliant and they did not disclose it when they sold it to me. 

So the land costs $300000 and it has curbs and gutters and to build 10 beds which is a teenie tiny operation you need showers, sinks, a nursing station, electronics and ADA compliance so to build a 4000 square foot place it's going to cost $1,600,000 (architect's plans, cost breakdowns, contractor. permits, state inspections...)   

There's always a need for more ADA compliant STR, so I would try to make the property accessible to those with disabilities. 

ADA issues grandfathered in or do you need to fix.  

This could mean apropriate fire suppression throughout the building, potentially adding elevator, full ADA compliance, etc.  

I have a contract on a 14 unit, 9 Baths, community kitchen/bath, ADA compliant,  single room occupancy.

See number 2Sometimes defining your objectives will help you answer your own questions.I look ar it as define your goals and make a plan to execute them, those may change over time & that's good because you're evolving ad a business owner.Dont forget your holding costs, taxes, builders risk insurance, utilities, security etc.Remember to manage everyone & be on site as much as possible.
