Where did you research sites to buy? Places like flippa seem sketchy, though I remember patio11 recommended feiinternational.com when he sold his business.
Yea i found one rare gem on flippa. Feinternational is also ok but both are limited. Flippa is mostly low end and fe is mostly 50k or more range. Honestly, look for word of mouth if possible too. Niche online communities are a good way to find potential sellers/sales
The key is to find them before they Flippa.i if you peruse forums you will find threads of ppl contemplating a sale, asking for advice. Get them there.
