It is an entirely online business that has garnered a great reputation and a lot of my business comes from referrals and word of mouth.

Even if it was legal you run several risks.  1) You would permanently damage your reputation in an industry where reputation is vital to get deals.   2) You risk major tax implications related to large capital gains.  3) Comps are not solely based on on the units you want them to be based on.  4) Even if this hypothetical plan worked exactly as you laid out you would be extremely over leveraged and underwater on the other units as you pulled out falsely inflated equity. 

Plumbers come in many forms, but from my experience reasonable and reliable don't go in the same sentence.

I had water coming from units above in my multi families and plumbers who came usually checked to see if the overflow drain is working.

Can anyone share reviews if this website is reputable?

It must be a major name lender or a local mortgage brokers with good reputation. 

once you get a solid reputation in Fresno, realtors will put your properties at the top of the pile when showing, vs the bottom of the pile for most flippers which is what I do right now.  

Do anybody know if these are reputable people??

My main plumber has a connection with a licensed plumber for when that is needed. 

No wonder we as landlords have a bad reputation.
