Very familiar with the area as much as most people want to believe gentrification = safer, it still has its high crime due to the extreme ends of diversity.

Rents are strong there and it is a diverse city for employment. 

STRs have great value in a city like Boston as we have year-round demand for short term housing due to a diverse economy.

It’s a great city with diverse employers and business friendly laws.

Florida is about as diverse as California is with dramatically different markets.

They'll provide the real insight, but here are some metrics I look at:-Population growth-Job growth with higher wages-Business friendly-Diverse economy-Strong occupancy rates-Acquisition price-to-rent ratio-Landlord friendly-Infrastructure development-Lifestyle amenities-EducationBest of luck!

While I feel like Denver will continue to stay high on that list for a little while (the diversity of our economy, the tech money coming in, the potential for mushroom exploration make it a multi-faceted place), I would note that in Denver, the rents have not met the mortgage yet, so it's very hard to get good cap rates or cash flow in Denver- despite the demand.
