Even when I occasionally have access to the MLS, I prefer to use other platforms that have better search parameters and format.If you want a real advantage, go get a General Contractor's license....but even then it's dubious if you're just working for yourself....

We live out of state but plan to use it occasionally for next 2-3 years then sell it or rent it out. 

I also do not go out looking for listings or buyers (except for investor/developer buyers in Los Angeles) as our license is used for our own acquisitions/dispositions and that of our developer clients with the occasional friends and family listings.

You only have to check it occasionally to see if you have competitive prices.I don't know of a fully automatic way to do this and I don't trust the Airbnb/Airdna or VRBO suggested prices.

We do occasionally find deals on the MLS where there's enough equity to refi after a rehab, but those are RARE.

I see you had paid an ADU consultant, did they mention that CalFHA has an ADU grant program that dishes out up to $40,000 for these "soft costs"?

The HELOC's do not, the HELOANS occasionally do. 

Real gems can occasionally be found hidden in places where the urban wave is just beginning to take hold.But just to let you know, finish your homework.

Be prepared for chilly weather and occasional rainfall.

and had glitches occasionally, they always followed through so the end result was to client’s satisfaction.
