The best market for YOU, is the market that fit's YOU; you're situation, your preferences, you're resources, your knowledge level, you're risk aversion and about 40 other personalized factors to you. 

Every single cabin I build is a deal I'm going to add 150k or more in equity (I've done a couple of larger ones that have 200k to 300k in equity) and anywhere from 5k to 10k a year in net profit by year 2. 

Most of my funds are in flips though, and small faction in stocks; i prefer some diversity, and cryptocurrency is another option to branch out too.
