What information do i need to check?

I would also double check all of your lease documents and make sure everything is in compliance with the local ordinances.

Am looking to buy a multi unit property in Columbus and trying to estimate what the property tax would be.I checked in the Franklin county assessor website and was able to find a property tax estimator.

Double check that TN, if that's where the property is located, is a quick-foreclosure state.

That being said, when I was younger I found one bad habit created by updating and checking my PFS (net worth statement) when I wasn't required by lenders to keep it.It can be de-motivating at times. 

Thanks for the recommendations @Kevin Hintz, I'll make sure to check those out

To use the insurance example above, looking at what the existing owner is paying is a great check on if your estimate is correct.

I can make lender recommendations, but one piece of advice I tend to give is check out the 203k endorsement summary (just google it)HUD each month puts out a list of lenders that have written 203k loans in each market.

Work with a real estate agent Make sure to thoroughly check out potential properties by conducting inspections, condition assessments, financial analysis, and reviewing zoning regulations.

I tried bender rentals and property management I’ve been with them for 5 years , no problems and I’ve been getting my check every month, I tried almost all of those property management in Milwaukee they all crooks
