Second Mortage/ HELOC to buy an Investment Property?

[Chris Smith]

Hi guys! Hoping for help understanding the best way to finance a property I'm interested in. Obviously I want to reduce my cost of financing, and with Investor loans even more expensive I'm looking for other options. Would a second mortgage/HELOC on my primary be an option and then make an all cash offer? My house is worth ~$650k and I owe $200k on it. Also, I have another property (Condo, paid off, worth ~$300k, rented to the same tenants for 9yrs) that I'd borrow against as well. Any help would be greatly appreciated! Chris
