Hi Raquel,
I am also a veteran. I bought my first house, a townhouse in Northern Virginia, back in 2011 with a $0/down VA Loan. I just refinanced out of it in October into a conventional loan. We signed papers on a new townhouse, basically the same as our current one, and it will be ready to move into late July. We have started getting this one ready for renting out (packing, painting, getting rid of things, FB marketplace, etc.). Next step is making sure my LLC is where it needs to be, setting up a small business checking account, Wells Fargo has been my go to for their low requirements and fees at startup. Then, I will subscribe to Quickbooks and create an account on Avail.co to list/rent this house. QB is mentioned so many times here, I feel like it is the best accounting app/software to start with. Been checking out various apps for the listing, management, leasing, and rent collection and I am being pulled towards Avail. I was going to go Cozy, also from reading so much about it on these forums, but they partnered with aparments.com and *most people seem to dislike that. I will replace my hot water heater as well before I start the rental process so I don't have to worry about it for the next decade.
This is what I am doing to start my journey. I hope it helps to see where someone is just a little bit further out than you. To me, it seems more realistic than hearing about 100+ doors. One thing is for sure, you have to have at least one to start! =D
