@Dave Spooner I have not sold it, but an identical replica of the house ( this is a tract home) sold last month for 535K in worse conditions. 

In order to keep the liability protection on the homes owned through the LLC, I need to maintain "separate identities" between myself and my LLC. 

A professional manager will:1) Limit the risk of lawsuits and risk on tenant safety2) Perform home turns between tenants quicker than you can3) Screen tenants with advanced knowledge on Fair Housing Laws, identity theft, and filtering false references4) Be able to monitor and handle scams5) Provide you with the quickest eviction process if needed6) Have problem solving skills, so that most days you don't even know there was an issue because it resolved with little or no involvement from you.7) Have resources that include eviction attorney, repairs, cleaners, appliance repair, screening companies, mortgage properties, emergency line coverage. 

Those numbers are identical to the neighborhood I live and invest in.

If two identical properties next door to each other both sold on the same day, one for $500K and one for $600K, my county would later assess them both at the same tax value.

Is your rehab process identical to that of other flippers you know?

Also you would be violating the NJ Landlord Identity Law by not registering. 

(but not zoned for) Property is currently offered at 750k , a property right beside almost identical was sold for 725k on conventional mortgage and it was initially offered for 769k. (5.72% decreased on a conventional mortgage that took almost 4 weeks from pending to sold).So based on this data I have estimated(not exact science) that I could give a lowball cash offer for 550k(maybe w/ some luck) but with some room to go up to 635K (which is a 14% decrease on the listing price and hoping to close fast with a cash offer) 70% of $900k is only $630k, which would be the max you could refi. 

@Levi Davis We went through a nearly identical situation last year.

This plan does not avoid capital gains or keep his identity secret.
