Solo investor - how much scale to have steady, livable income?
I'm wondering how investors who don't collect AM/Acquisition fees (i.e. don't syndicate) are able to live day-to-day off of just the money they make from their real estate investments. It's probably close to impossible to get that going in today's market, but during "normal" times, what level of scale does a solo investor need in order to make a livable income net of any business expenses? The goal would be to have the property pay for itself while building equity, all while floating a moderate lifestyle that allows you to continue your life as a "career investor"? This number would be different based on several factors, but let's call it $7k/month ($84k/year) take home, net of all business expenses.
Another way to phrase this question - generally, what would one's personal real estate portfolio need to look like for them to be able to go out on their own and live modestly off of their investments while their wealth compounds itself?
