Buy All Cash or Finance?

[Gil Pang]

Hello BP Community,

I'm currently in the process to purchasing a 2 family home for 37K.  (probably will be appraised in the low 40s)

I'm currently putting 25% down and looking to finance the rest on a 30 year loan. ( roughly 4.5%)

My friend who is a LO told me why not try to pay all cash for it and try to save on closing cost?

If i were to gather funds to purchase all cash, this would leave me tight and not much money for savings or making the necessary rehabs.  

What is my best route to take?  

I was thinking, buying all cash. Then put a HELOC on the house to do repairs and make a move on a second house.

Or just stick w/ my 30 year financing.

im open to any other ideas.  Thanks in advance!
