Hi, this is exactly how i got started:
Instead of focusing on getting a team, i would seriously consider joining a team. a 9-5 is nice but gaining the real estate experience that comes along with the job will become much more valuable then the W2.
When i started out i had neither money nor credit, with that being so, time (availability) and experience was the key. leverage your time to gain experience, leverage your experience for credit (credibility). credibility and cash, for your lenders security, will bring you the credit that is necessary to ramp up your buy and hold business. in that order lol
there are plenty of financing options out there and with time they will find you. Co-signer doesnt even belong in the realm of investing, you've got a lot of researching to do. there's seller financing, lease-options, hard money, private lenders, and the list goes on none of which ask for co-signers.
I would join a team of wholesalers. become a bird dog and learn what a good deal looks like. attend rei meetings, build a network so when your ready to strike you will have the resources to do so.
