I'm thinking of leasing a vehicle. I already own one car, and my husband would use it if I get a leased car. I run my own business, and heard that I could write off the lease. I'm not sure how write offs work, and how much money that would actually save me when taxes are due. I also don't want to keep the next car I get for more than 3 or 4 years, so I wouldn't want to buy the car after the lease is up.
