I have multiple listings in Kenosha and Racine and this is the first time exploring the investment opportunities in the area.

They would keep it on their books because Fannie Mae or Freddie Mac will not guarantee it for one reason or anotherA portfolio loan is a loan that encompasses multiple properties. 

Even if he solidifies my $1330/acre number or adjusts it, I still don't know if the value of the pine left growing intact on the land is equivalent to the harvest value or some multiple of it. 

I question how dedicated the guy is to selling the property since when he was selling two other properties for me to 1031 into this 30-unit he was communicating weekly if not multiple times per week (a good amount of commission was involved).

There are specific strategies you should employ before getting going with multiple properties, but you're pretty far down the road and I'm not sure you will want to or be able to put the toothpaste back in the tube per se.  

@Jacob Calbillo there is no minimum amount of homes - the definition of a park is multiple mobile or manufactured homes on one piece of land that is usually owned by someone else.

I offered $52k and seller accepted, multiple contracts fell through already, I was told.

It sounds like they have multiple complex issues going on they cant solve to move it.

You can get a blanket loan for all the 4 units if they are separate owners.Even if they're purchased in separate transactions with multiple owners, you still should underwrite the whole portfolio as one for future projections, depending on your exit strategy.How you present the proforma and executive summary to the lender will depend on how you purchase the assets.

My end goal is acquiring multiple properties as mentioned in the Bigger Pockets article “A Slow, Boring, Incredibly Awesome Strategy...Real Estate Investing”.
