That's great you're starting out in real estate early! To answer your questions:
- Save up any money you can, but start learning how to use other people's money to buy real estate. Not only that, partner with experienced investors who can partner with you on these deals
- Usually it's a personal preference on which market to choose. It's best to start in your own backyard, but if your immediate area has less than 400,000 residents, then consider going to a virtual market
- Connect with as many agents, contractors, property managers, attorneys, and title companies as you can. Start now as you work on finding real estate opportunities
- When would you like to start purchasing your own real estate?
- Mortgage/rent ratio is pretty subjective. Me for instance, I would like rental properties to cash flow around $300 a month after all expenses. Everyone is different though
- I heard Louisville KY is a great place to buy rental properties, especially for people starting out. But make sure to do more research, connect with local agents that know the market, connect with investors who own rental properties in that market, and then decide if that's going to be your main stomping ground.
Hope this helps!
