An interest rate that works for her. 

You could also get a line of credit for about $150k (you should be able to borrow 75% of the value.)The reason I suggest this is…1) you save $40-$60k in selling costs. 2) you have a lower blended interest rate (2/3rds at 3.25% and 1/3rd at 7 or 8% instead of the whole $500k at 7 or 8%) saving you another $1k/mo in interest. 3) you only pay interest on that $150k when you actually use it, not from day 1  Unless you hate this property, or want to buy something you can’t afford without selling, that would be my plan.

The tax advantages of buying/holding gas stations are pretty great.Many of the components of gas stations including pumps, tanks, external parking areas, and other equipment are classified as either 5 or 15 year property so you can bonus depreciate a lot of it (minus the land value) and get significant deductions in year 1.With the 2025 bonus depreciation rate at 40%, a $1 million gas station acquisition could still lead to $100K+ in year 1 deductions depending on the specifics of your deal.

So on page 6, Modern Money Mechanics: Federal Reserve Bank of Chicago, it explains that banks don't "pay out" the funds for loans from money in other depositor's accounts.

If a bank has to pay out 5% to get deposits then they usually want 7% to lend back out or it's not worth their time.
