If you have a Fannie or Freddie mortgage, there are specific guidelines on what happens in these situations. 

If it's a fannie or freddie loan (ie, 30yf), you're looking at 25% down.As rates continue to rise, "quotes" and the like are meaning less and less as the refi jockeys scramble in desperation.

There are 2 units above and one of them already gave their 30 days notice and it's okay.

First, you aren't permitted to borrow funds, unless those funds come from a piece of real estate, to purchase an investment property with a conventional loan (meaning Fannie/Freddie loans).

Anyone offering loans with an ROI for the lender below an index fund better have a good explanation for why they are doing that.To wit: The 30YF Fannie/Freddie stuff can be down below S&P 500 index fund because Fannie/Freddie purchasing it on the secondary market amounts to a big fat subsidy. 

You didn't mention what type of property you are looking at but if it's a single family home then the Fannie Mae Homestyle loan is a good option. 

Make sure you give proper notice to discontinue the lease at the end of June, most states is 30 days unless expressly noted in the lease language. 

These types of properties are not permitted under current Fannie Mae/Freddie Mac guidelines. 

We gave the old tenants 60 days notice and renovated each unit. 

That precludes Fannie and Freddie and makes the rate jump into a different strata.Stephanie
