Side note: The financed property limit used to be 4, and even though Fannie Mae increased the limit to 10 in 2009, most banks still don't like letting you have more than 4.

There are multiple options like CBMS, Bridge Loan or Apartment Building with 20% from Fannie Mae. 

Hey RyanFannie Mae and Freddie Mac will guarantee loans up to 4 units, so lenders consider anything over 4 (like your property) commercial.  

Fannie Mae, the government sponsored enterprise who sets loan guidelines has set specific guidelines for lending money to condo buyers.

Quote from @Molly Francis: Anyone know of any companies similar to Sundae?

@Jack Little Generally speaking there are 2 main types of loans for investors: “Conventional” and “Portfolio”Conventional - I'll define these as loans that come from Fannie Mae and Freddie Mac (if you recognize those names).

Meaning, not Fannie Mae or Freddie Mac loans. 

the only thing to be aware of is that Fannie Mae (conventional financing) will only allow for up to 10 financed properties. 

These listings are directly from the bank that owns the property, HUD.gov, Fannie Mae's HomePath.com, and Freddie Mac's HomeSteps.com. 

Conventional loans (from Fannie Mae or Freddie Mac) for example, have concession limits of 3%,6%, and 9% depending on your downpayment amount on a primary home.
