I want to become a "used" car dealer and start selling cars privately. I am thinking of buying say 3-5 cars around 3k-20k range. Keep the cars in my home garage. and sell it privately by listing it on autotrader, craiglist and other websites. I have quite a few questions regarding this:

Can it be done?

Is it profitable?

where do most used car dealers buy their cars from? can you list the sites?

how does the whole process works (from buying a used car to selling car), please explain it to me in complete detail?

If you buy the cars from an auction, can u test drive and have your mechanic look at it or find out good and bad about the car prior to bidding?

I am very new at this and dont know most things about this business but very eager to learn and hopefully run a small business.

thank u for taking the time to read and answering questions

what about the following ad? Do you think it's good investment?

I am thinking of buying a 4-plex. the cost of the house is 175,000 dollars. After 25% down, I am left with 125,000 mortgage. My monthly mortgage is close to 1300 dollars for 10 years. My house is rented out for 40,000 a year. After all the expenses EXCLUDING the mortgage (utilities, property tax, maintenance, snow removal, gardening etc). I am left with 24,000. When I take out the mortgage amount, I am left with 700 dollars in my pocket. I am also working full time. I am hoping to maximize my mortgage payment, and hopefully pay everything out in 5 years instead of 10. After 5 years, I will have roughly 2000 to 2500 dollars in my pocket. My question is, what do you think of the current situation I am in? And, how to avoid paying taxes on 700 income from rental property and 2000 dollars 5 years from now? Do you have suggestions? I am up for any advise. Thanks!
