I have 2 scenarios coming up where I will need to do a commercial appraisal on some of my properties to utilize the equity that I've created. 

What I wrote above does not create an attorney/client relationship between us.

I've done it several times and it's created financial freedom for my family and I.

In California, the Realtors Association actually created an advisory form just for this reason: https://www.car.org/-/media/CAR/Documents/Transaction-Center/PDF/Standard-Forms/December-2017/WFA_12-17_Draft9.pdf?

But, since we've had incredibly low inventory recently, and the number of homes on the market now is still lower than it was in 2012-2014 in this same time frame, AND the fact that jobs are still being created here (Google and Apple building new campuses for example), I think a slow-down is still a ways off.

(make sure your contract specifies that you get deposits and pro-rated rent when you purchase)Only thing you can consider requesting is that the tenants be put onto a new month to month lease. the benefit to this, is oral leases can only convey rent amount. this lease is created by accepting rent from the tenant every month. every other stipulation defaults to state law. this means tenant can show up tomorrow with 3 pets and you cannot do anything about it (except provide notice of lease termination) whatever you do keep the current tenants on month to month.

(atleast for the first couple of houses) Then im hoping i will be ready to do some larger more extensive remodels.I am looking to create enough cash flow to quit my job and eventually go full time flipping and BRRRRing.

I think you just have to interview a bunch that you trust and create a team for yourself.  

What usually happens is the people who book the larger units (usually 2-4 people) tend to sleep in a different bed every night, which creates more cleaning cost (about 2-3x the amount of time to turnover larger unit).
