I don't think you know enough to consider real estate in the short-term.

Consider different strategies like mid and short term rentals as I believe the Portland area would allow for success in both (although I have heard Portland proper is tough on STRs).Best of luck!

Also, consider builder incentives like rate buy-downs or upgrades if they’re not open to price negotiations.

It's been great - the property is 100% paid off and the house is worth 300-340k generating approx $2300/mo (that's after utilities/management fees etc.)I'm considering selling the property to buy 3 more within the same price range in the same market. 

2 or 3 bedroom properties would be more profitable considering their cost?

I am considering starting a new REI Meetup for Redding members of BP and the public at large.

Best practice is to ask them if they consider hard money cash. 

Again, if this becomes an issue in the future for your other tenants, then I would consider not renewing their lease. 

@Christopher ReidIf you're looking for asset protection, you might want to consider more than just insurance.

I have real estate agent will consider this person to manage as well not sure yet.
