Hello Neil,I recommend checking for companies that invest in themselves by being members of local realtor boards , local and national associations like NARPM (National Association Residential Property Management). 

Check to see if your jurisdiction is SB9 friendly and check the zoning on the current parcels  ADUs can be rented long term regardless of owner occupancy on the property.  

I'd check out Killeen/Harker Heights area. 

If permits are needed, you must check to see if you can pull them as the homeowner or need a General Contractor to do so.

They are out 2x a year servicing and checking.

chat with everyone. everyone. i talk to people in line at the check out at stores. you never know who you will meet. some people cant do this. or wont. we can fix cant.

If the local zoning permits it, you need to check your condo/ HOA association next: most of them don't allow short-term rentals but some do.

The huge negative is that you're not there in person to check on the properties frequently. 

I'm trying to help out other CA investors (I still think buying locally is better than an inexpensive property OOS where you can't check up on the property)I don't know the Peninsula well but expensive Palo Alto, Los Gatos, Cupertino would be Class A to me.

Check Your Area’s Water Level: Often overlooked, especially by new investors unfamiliar with septic systems, the effectiveness of a septic system hinges on its leach fields.
