Can any of the mortgage lenders on here give me an idea of what the general premium on the interest rate should be for a second home mortgage vs. a primary residence mortgage?

Depends on how much down and what type of loan. if you go with a conventional loan there is a pretty large premium due to relatively recent changes by Fannie/Freddie in what are called loan level pricing adjustments from second homes. https://singlefamily.fanniemae.com/media/30326/display

We do have products that are not conventional that would have more or less the same pricing on a second home as a primary as long as you have good credit and are putting at least 15% down.

Jay is a second home just that, a second home, or is it any home additional to primary residence purchased for any reason?

Those are fantastic
Is that a jumbo portfolio product?

Confirming and jumbo rates are the same on this.

a second home is a vacation home. One that you use personally use as a vacation home.

Sorry to rehash this again, but I need a sanity check.

I'm talking to a local mortgage broker because he's approved by my builder, and by doing so the builder will pay the title policy and the broker is "giving" me a 1% credit toward closing costs.

For a second home mortgage, he's quoting me a rate of nearly 7%, with hefty discount points. Just so you have more detail ... price of house is basically $500k and I'm only wanting to put 10% down. I could do more but I'm wanting to conserve cash. At last check (less than a month ago) by the current broker, my credit scores were 785 / 795 / 786.

I was initially intending to use this house as a second home, but given the current circumstances I'm now considering using this as my primary residence and putting my existing house on the market sooner than originally intended. I work remote so that's not an issue. Doing this would allow me to finance the new house with a primary residence mortgage. For this, the same broker is quoting me nearly 6% with 1% discount point.

I may be off base, but both of these seem high. I feel like he's quoting me high to make up for the 1% credit he's "giving" me, and maybe somehow making up for the title policy the builder is paying.

Any feedback on either of these situations would be greatly appreciated. I understand if you can't give me specific rates, but directionally, are these rates way off or not?
