Look up Michael Blank and apartment investing together and you will find a great resource who is giving a ton of info away from free on how to start in apartments.

I'd greatly appreciate any advice and more than happy to share additional information if needed. 

I guess it's just too many factors to consider and it easy to get overwhelmed and cannot get accurate info and estimation when I conduct analysis (ex. property tax rate, insurance, maintenance fee, rent, repair, closing cost, etc.) 

This poses an additional challenge for new RE investors.  

i don't know if you've owned any before (feel free to chime in with more info) but the costs of entry get understated. 

Quote from @Cody Maxwell: @Jay Hinrichs Thank you for the info Jay.

Just read the beginners guide - what a great resource - full of great info for someone just starting. 

Some additional details needed:1.

.- Additionally, you can track income and expenses consistently using software or spreadsheets.If you track everything, you could show a loss and use that to offset other earned income (such as a W2) which will net you a bigger refund.

This is great info, Mike.
