I currently own my home in San Diego, CA, and am looking for some advice on whether I should buy or rent out in Seattle.

Texas: Austin, Dallas, Houston, San Antonio2.

Selling our 2/2 San Miguel de Allende condo. 

the cap rate for single family in san jose is maybe 1-2% ; DSCR is 0.25 ; but with very creative strategy we can make it into 0.8-1.1 but the key is using more tenants per unit, also home that has basement and ADU like me, the unit can be rented and while my dscr is above 1.0 but banks can't use it so we kinda stuck to leverage but this creativity of multiple tenants per single family.i am now trying 40 year IO program from one of the lenders such as yours to quality, also i will try no-ratio DSCR at some point.Seriously, by combining hefty cash position + flip program + rent out to multiple tenants ; and sell it few years later, this is the less riskiest project we can do as landlord/flipper.

I'm in Helotes but invest in San Antonio.  

San Antonio seems like a shoe-in.

My first STR experience, some 5 years ago was in San Francisco.

There are many other places across the USA with much higher returns- Myrtle Beach, Ozarks, Hocking Hills, Tampa, San Antonio, etc..  

Here's scenario:In my early 50's married with 2 kids, good income, live in San Diego, CA.

I see you are from San Antonio.
