Thanks for the Info, for me unfortationally  all my properties are located in the largest county Jefferson County and they love to put out of state big investor companies so they can put the extra money in their account and if you get behind on the propert taxes 1 year they require that you pay the overbid interest amount AND THE NEXT PROPERTY TAX BILL TO REDEEM,That's a big hard ship on the common resident to come up with 2 years of property taxes and Over Bid plus 12% interest dailyBlessings to All

@Marisa Faulkner also, make sure you account for self employment tax, which is an extra 15.3% tax on top of your regular income tax.

A good strategy is to compare areas and see which best suits your situation and then become an expert in that neck of the woods - find the best investor-focused realtor, etc.About your second question, I am not a lawyer or accountant so you will need specialist advice there.

Should I have all expenses and income in one bank account?

@Kendall Smith@Michael Plaks is an accountant in your area.

However, I believe in most states if you can locate his bank account that there's an avenue. 

Did you complete a final accounting after the tenant vacated? 

Also, If I am house hacking do I still need to have a separate bank account?

I also am studying an accountant program, and I also want to change jobs into that field as it will double my personal income, and thus increase our capital and reserves, and also benefit our real estate journey through the knowledge I will gain.
