That might be one way to go if that is your only source of cash to start your REI.Also, some plans let you borrow against your retirement account so you aren't actually penalized (by the IRS).Good luck.

Will I need to buy new window units with a heating source or can I provide future tenants with space heaters?

My favorite part was there were zero surprises because it was new construction. 

., cash out 200K, buy a 2-plex for 200K for "cash" to make up for the negative CF of the source asset. 

My favorite is cash flow.

Developing systems to source solid off market deals will help open doors to other things you need to ultimately be successful.

If you are wanting to take the money and pay off debt incurred while purchasing/renovating the property then you should do a cash-out-refi.... if you are wanting to take the money and use it as a short term asset source (such as using as a down payment on the next BRRRR deal) then you should get a HELOC.

Quick phone call and you get it directly from the source.

It's also for people that just do not want to handle that part of development and source it out so they can spend more time on finding and doing deals.  

Will you funding source have to pony up that cash/credit or will you?
