Computer or Smartphone, an internet connection, a blank Purchase and Sales Agreement, and Assignment Contract, an investor friendly title company or lawyer(depending on which one your state uses for closings), a bank account..

On-line Auction Foreclosure Website.

Look online for https://kscore.kw.com/.

I purchased my first investment property through an online auction for delinquent property tax.

I would recommend making use of all the free resources available through BiggerPockets and the internet.

It would be helpful if someone can suggest one they like, I noticed most website just check the internet.

I just stumbled upon it online and I’m trying to research it myself. 

As @Ke Nan Wang said you have to hire an architect to make these decisions for you.On my projects I will compile like 5-10 inspiration photos based on projects I've done in the past, comps, and photos I find online, then I'll present those to the draftsman/architect.

What I'm really looking for is a simple platform where my tenant can pay rent online rather than send in a physical check every month (their current system...).

I would do some online research into Realtors in your area to see if you can make a connection.As @Michael Dumler pointed out, wholesalers are going to be a more reliable source for consistent off-market properties with margin.
