Any experience and suggestions?

@Jerome Morelos Definitely look into your state laws...I know here in MA I am not allowed to charge tenants for water UNLESS it is sub-metered correctly.I am also required to provide heating no matter what during "heating season" even though the heaters are also separate for each unit.I would also suggest taking a look at other listings in your area to see what common practice is.Best of luck!

I would highly suggest going to some local REI meetups!

I suggest you keep looking.

I would suggest, in similar fashion, start writing out your investment strategy so that you have a road map to where you want to go.

I'm wondering if there are other BP'ers willing to take a look at one of my deals to see if there is something I'm missing in the analysis or if there are assumptions within my deals that I'm underestimating.Here is the link to the deal - https://www.biggerpockets.com/calculators/shared/916449/7da6c614-e8cc-41b9-9e15-965565b159baAbout the assumptions:This is the Charlotte NC areaPurchase price shown is the current asking priceProperty taxes are from the assessor's office and the monthly income is the average for 2 beds in Charlotte.My goal for deals is cash flow.Any and all thoughts/suggestions are welcome!

I highly suggest you to read, "The Ultimate Beginner’s Guide to Real Estate Investing".
