As far as property management goes, I found a lot of the easy-to-get property accounts are the most difficult to collect and manage. 

A few notes from a licensed insurance agent:$500,000 liability coverage on renters insurance is not difficult or expensive to get.

other methods still work but are difficult right now because interest rates and prices are both high.
