We did this on a SFH that was our first house, we lived in it for two years and rehabbed it, that paired with appreciation between 2015-2017 netted us a nice profit.

Do you have partners to pair up with to be able to meet lender requirements?

There have been several cases where something unexpected came up, and this let us solve it, f. ex I did a pair of identical duplexes right next door with a shared driveway in the middle (but it was marketed as a fourplex) a tad over a year ago in Vallejo...

Ironically, it actually discouraged me from building a permitted ADU and opting for a nonpermitted basement ADU for au-pair quarters and later on airbnb (STR not allowed for permitted ADUs/duplexes etc) which seems to be a better return on investment vs. long term renter if living close-in. 

We are renting one half of the duplex to a pair of college kids close to the property.

The very basics of this new deal are a pair of 4-plex properties (very nice properties) that generate in excess of 4k a month in rent that I am negotiating to purchase for 175k cash, but actual market value prob 225k+ conservatively.

All of the above paired with the big neighborhood shift at W.

Refinancing pairs debt called a mortgage with a property. 

One funny thing about the guys is that they would rather buy a new pair of socks than take their dirty clothes to the laundry.

Feel free to connect with me, it would be awsome to pair up with someone who is just beginning like I am and help each other out.
