Is 13% APR for a HELOC high?

Having this on hand can make your offers more attractive because it lets the sellers know you are a step above a pre approval - your file has passed an underwriting review.

Bank of America Cash Rewards and the American Express Blue Cash Everyday card give you cash back for spending something like $1000 in the first 3 months and have 12 or 15 months 0% APR.

The generalized advice would be to get your tax id and bank account open first, get a pre-approval on a mortgage to know how much you can qualify for and under what conditions.

They also rented ski/fishing boats to guests for additional fees.

If you're super close to one of the ski resorts you can also rent for winter weekends (though the ski season has been getting shorter recently).

I use Chase Business Cash, 0% APR for 12 months when you sign up and cash back if you spend x amount in the first 3 months.

You never get married without a pre-nup and you never form a business without an operating agreement.

If I have a pre-approval for a purchase in California, can I use the same approval for a purchase in another state?
