Yes, the size of your down payment matters – but not in the way you might think.
Depending on your personal situation, you may want to have more cash on hand to invest, make repairs, or for an emergency fund.
On the other hand, your priority might be lower monthly payments (and avoiding PMI could help you get there).
Whatever your situation, just remember that there are a lot of loan programs out there, and it’s your loan officer’s job to help you find the right one for you!
