FROM MONEY It's About to Get Easier for Over a Million Homeowners to Refinance Their MortgagesTwo new mortgage refinance programs launching this summer should make it a little easier for lower-income borrowers to save on their home loan payments.Starting on June 5, Fannie Mae will offer a product called Refi Now.

As a side note, regardless of your brokerage once you get a certain amount of transactions and experience you can opt in to Redfin's referral program.

They might have special programs that could save you money, by way of lower rates, or give you different financing options.

The reason they don't like this is many people commit mortgage fraud and do not actually occupy the properties after purchasing them with a low down payment option such as FHA or a first time home buyer program. 

I was considering to accept a tenant from section 8 program.

Yes I get it, Stessa is a free program, but I have years of data invested in this program and I am trying to resolve an issue that’s now 2 months old..  

I am looking for a solution which I can send out leases to tenants for pre-leased units and then ultimately hand them over to the property manager once the project is complete.
