For perspective, last April I closed on a new construction loan (build to rent) with a turnkey company there (Rent to Retirement).

Purchase the first one cash (to mitigate risk) and the second property with a loan.

I paid $600k and got a local bank to loan 75% for 5-years at 3.85%. 

I found an apartment for sale with an assumable loan.

I am pursuing Fannie Mae’s 5% Down Multifamily Loan.

This way the commissions get rolled into the loan (in most cases) and buyers (most of whom are using financing) don't have to pay their agents commission out of pocket in addition to their down payment.

You will need to make sure you meet all the lender's requirements if you are planning to buy with a loan. 2.

They want to put 75% leverage including interest only 3-4 year term loans on their acquisitions. $600M total potential acquisitions.

I loaned to an LLC for a flip.

Also, compared to a traditional loan (i.e., conventional, FHA, etc.) for a primary residence your rate/points options are going to be higher for an investment.
