Applying for a HELOC: with 20% equity in the residence and considering taking out a line of credit to fund a down payment for an investment property in Chicago, Austin, or Pittsburgh.  

Just wondering is there any bank that will do a decent refinance with a credit score under 620 apt is being rented out now its a manhattan coop with alot of equity.

I'm closing on a house and plan to refi another house next so that means I can't make any credit moves for another 6 weeks or so.Thanks 

Depending on credit score and other factors, FHA or conventional may make more sense for one person over another.  

That means be prepared for very slim cash flow, keeping money tied up in reserves, and concern yourself less with how much money you can pull back out and look at the actual numbers.

I have a long standing relationship with my credit union. 

Go to a local credit union.

Should I start with any credit union or Lendingtree.com etc or any other source?

And you're probably going to pay 3 points or so upfront for that hypothetical hard money 2nd mortgage on an investment property to 70% CLTV, assuming you could get it.I don't have any credit reports in front of me, but I'm pretty sure you can do a little better than 4.83% at a cost of three points.

Along with a credit report, I have read that other documents for a rental application should be included.
