I have experience with automated data extraction and manipulation, as well as, Geographic Information Systems (GIS) and spatial analysis.  

On the other hand, I could refinance and extract the equity this way, but I really don't want to always owe a variable percentage on ALL my properties at ALL times to extract the equity on all of them, as the risk is bigger for me in case I have too many vacants and because nobody will lend me more money if I owe money on everything I have...How have you guys solved this problem?

Ready to extract everyone's expertise in the industry.

Extraction is drying up already, and those that stay alive will be much smaller. 

Hello BP I have a question a family member is willing to pass on a duplex in Los Angeles worth $450,000 he has $200,000 in equity which he wants to extract and I just keep making the monthly payments of $1300 and pay off the rest.

Here are some questions I have as a newbie starting their journey in REI1 - Would refinancing a primary residence to extract the accumulated equity be a good source for financing the down payment on a buy and hold property intended to be used as a rental?

Would I have any options/workarounds to extract the maximum equity back from the property in a loan?

That means a lot of different things to peopleI am in the wealth creation mode, so my strategy has been to purchase undervalued multifamily properties, force their appreciation, refinance the property to extract money, and repeat the process.  

Seems like for that particular area, rentals extract more value for a property like yours.

They are doing something right, they aren't extracting huge listing fees out of us.
