I am out of SC and invest as well as help investors. I agree that you want to vet your team in or out of state. Make sure your realtor knows investing language and how to analyze. Find an insurer that is a risk manager not just a salesperson to sell policies. A good team no matter where you go is key to being successful.
Regarding estimated costs- here in Charleston area, each county has a tax estimator to use for that purpose but each area will be different. Insurance, ask an agent to help, bring in the WHO's, your team.
Regarding numbers, make sure whatever you decide it is actual cash flow. It isn't just PITI then that is your cash flow, build in maintenance, cap x, vacancy, here we have a termite bond. Then your ACF is after all these things.
If you can start with a house hack, whether multifamily or find a home you can add an in-law and rent out the rest of the home, this is a great way to get into investing. You can get your living expenses down really low and save up money for more investing quicker.
Go get it!
