sweet spot in renters

[Account Closed]

My main source of income is now from my rentals. The question I would like to ask is  there a thought on who makes the best renters.

 Shld we be concentrating on low or high end?, millennials or baby boomers

In an economic downturn, what types of renters are least likely to default on their rent payments?

Is it better to leverage or pay down existing mortgages?

Buy new properties to offset rental income with depreciaton write offs? meaning leverage more to gain more depreciation write offs
