I think Park City is one of the best places in the USA, great skiing, biking, hiking and golfing, and only 30 mins to an international airport. 

It is a very desirable location, close to new business and the IAD airport, plus offers easy access to the Dulles toll road and there is a metro line that can take you to DC in ~45-50 min (although you work from home, your tenant pool and what you can charge for rent will be considerably higher thanks to easy commuting options).Some of my clients have bought in that area for less than $400k (you can find properties in the low $300s if you are willing to put some work on the properties).

My area of focus was west of schillinger in the baker school district, and I bought in a neighborhood near airport blvd and snow road.

There's a lot of commercial building going on (shopping centers/major grocery stores/Hospitals & Urgent care centers etc. ) to accommodate the influx of people.There is also a lot of growth in Poinciana (adjacent to Kissimmee) with major development plans too.  

And from experience, now no longer consider the property if it is: on a corner lot, on a flag lot, adjacent to a run down singlewide, has little back yard, power lines in the back yard, too far from town.We have been living in each flip as we remodel. 

Strong demand (fastest growing county in the state), limited supply downtown due to the historic district, limits on sprawl into adjacent counties because of natural resource management issues, somewhat less onerous landlord regulations, and the ability to find some properties that cash flow at least a little bit right away.

. -- although even if you are in HPOZ, there's very little they can legally do to stop you do an ADU, especially if you aren't doing any substantial demolition, and there are ways around some of the hillside restrictions depending on where you are)Cost- It will depend on the condition of your garage's structure (footings, slab, wall framing, roof framing), the distance that's required for trenching, any electrical panel upgrades or location changes, and your design intent- Check that your garage has footings that are deep enough below grade (12" min in LA City, 18"-24" elsewhere) -- if not, you'll need to underpin or rebuild them- Check that you have concrete curbs, as these will help stop water intrusion from adjacent soil -- if not, you will want to find a way to add them, either by making the contractor do surgery on the building, or by adding them as part of a larger demo+rebuild strategy for the entire garage- Look at your slab.

A client asked me to make a post recently about the driving park neighborhood which is a part of 43206 in Columbus and directly adjacent to Southern Orchards and Old Oaks.
