Secure money for cash buy

[Ankit Maheshwari]

Hi BP Members,

I shortlisted one RE property with $350K purchase price and with good long term tenant income ($4400 PM current). But the buyer is asking cash only deal. I can get $90K-100K from my side. What are the ways to secure remaining money for this deal. I am open to any suggestion. 

FYI - This will be my first investment property.

Thank you in advance.
