I am planning to buy rental property in Birmingham AL.  

Im in the process of purchasing a brick 2 unit from them.

This will make the process a nightmare for you.

You pay for a service, and a good realtor will likely net you more money and help you navigate the process versus selling on your own (especially if you've never done it before). 

While we've had a fair number of clients pull off the full BRRRR and getting all of their money out, it's far more likely you're leaving $5k-$10k in the deal.I think that's pretty reasonable given you're out of state and not doing much to manage the process.

Any recs on companies that help form LLC formation, business structure and estate planning services?

The plan is to rent out the top unit to a long term tenant and for us to live in the middle unit until we move out (if we ever do). 

Finally, create a detailed financial plan that includes your home buying budget, loan arrangements, rental income and expenses to ensure that the investment remains profitableThank you!

To get into real estate investing at a young age with strong credit, think about plans like living in one part while renting the rest, making friends in the field, beginning with bite-sized properties, using savings and credit well, and eyeing areas that might grow.

Unfortunately I did not do the requisite due diligence early enough in terms of Zoning and I can not execute that plan.
