What is never said enough on this site is real estate investing is much easier for people with money, and the best first investment you can buy is an investment in yourself, up to a certain point ofc, before it's not worth it to overwork yourself and instead "parallelize" income with other properties/businesses.

Are there specific databases or resources that are invaluable for this research?

It would be a section 8 rental, the fair market rent for section 8 (hud gov site 2024) on that zone is 1200 for a 2 bedroom, since it's a duplex it has two units with 2 bdr so the total rent would be 2400 (both section 8 tenants).

This is purely a guess on how the site works, so I have now clue.At least in my area there is usually a phone number you can reach the realtor at or I just Google them. 

Local county records, zillow, trulia, any other big online site like that, hud homes, hubzu, spark offer.

I found out first hand that this list may contain what looks like comparison sites for the software I'm looking for. 

Here are some resources I found really helpful on my journey:1.

Finally somebody that can leave respectful and relevant feedback.

The site looks pretty solid and I could always have an attorney review after I put it together.

I joined biggerpockets a little while ago, but I haven't been on in a while because I felt like I had absolutely no experience so I wasn't really benefitting from this site and I couldn't really give any input.
