Insurance agents are a dime a dozen, I would first recommend getting quotes from your current provider of car insurance. 

Stop having a car payment.  

Get in my car, take a picture of the check via mobile deposit and were done here.  

When I see a car on the street with a For Sale sign, the one thing I want to know is the Price!

Hello Bigger pocket I Have 3 bedroom and 1 bath SF with Attached garage, I feel that there is not need for that garage because it barley fit a compact small car. at the same time  building a  car pool on the top of the drive way will fit the propose of parking  ( pretty common in my market)currently I live in the house but this house eventually will be for rent. so I decided to turn it into extra room and add extra bathroom. the question: what is the best use for this garage  Plus Bathroom? 

Newly remodeled, previously flooded, 18% cash on cash, 85% return on equity, 31k down, 4 junk cars next door in the driveway, quick access to hot part of town

You will either be getting singles or a couple in just a bedroom, so at most they will have two cars.

No car payments.  

I would continue to make your car payments on time and use the stored up cash for investing.

ROI is standard as wheel on the car, as profit is to business.
