What type of financing for this scenario

[Danny Price]

A friend of mine owns a wedding venue/equestrian ranch in middle florida, (South of Winterhaven) and is seeking to borrow against his property. 

Value of venue est. 3 million. Property has 2 residential structures, lake frontage, horse stalls, pens, etc. 

He paid cash when he bought it. 

He has zero debt. Owns 4 other lots and 2 homes in Florida and 1 in northern U.S. 

He is looking to get around 500K out, for 2 maybe 3 years. 

Purpose is to invest in municipal real estate auctions. (foreclosures, tax, trustee sale, etc) 

Financing type ideally: interest only or balloon. 

He has had many successful businesses in the past, all purchased/operated with no debt. 

Is this possible with Private Money Lenders?
