how to get money out of my properties?

[Mirzet Mehovic]

So I have a house got it for $380k, put about $120k down if I remember correctly. Now worth almost $800k according to zillow (if its accurate) but they don't even know all the work I completed(total rehab with top of the line stuff for myself to live in), may be more or less I don't know. 

Also got a multifamily for $75k almost paid off now on zillow the cost is not even listed I guess they assume its in **** condition like it was when I got it. 4 family 1 commercial space. Totally gutted and renovated, brand new. Got to be worth a lot more now. 

I need to pull out 150k-200k if possible. How do I do it? Home equity line of credit on the single family? Can I get the multi family appraised and take a loan on the appraisal amount? What are my options? Thanks for any advice you can give me or point me to where to find it.
