I've been buying and holding for SFH's rentals for 15+ years, but my goals now are Cash flow (70%) and Appreciation/Equity (30%) so I can invest faster/grow more in shorter periods of time.I ran this: View report on BP as a really rough test for investing in this property (3-plex, but also offers an attached 3-plex for consideration). 

The rental was primary residence for 10years and I’ve been out of it for 3.5 years.

Well since I spent the better part of 40 years in Bay area and 15 specifically in Napa Valley and the last 20 in Lake Oswego and have done a ton of business in Yamhill county and own property in mac and all over the foothills when I was logging. 

When we bought our house a couple of years ago, I never had the thought of renting it out rather than selling it.

I was actively searching a couple of years ago when I began considering them in addition to rentals.

(A year and a half ago.)Ok, how would you like to proceed?

We perform several flips a year when we find them from wholesalers.

As a note, I am active duty military, scheduled to deploy sometime next year, and I have plans to rent out the unit I am staying in once that time comes around. 

So what I do is, I stick them in a file in check on them every one to two years.

If you have a move-out every year, that would amount to a vacancy percentage of 14.3%; two divided by 14 (12 months tenancy, plus the two vacant months).
