@Jorge Vazquez we stopped doing signs over 10 years ago.We had a separate phone number on our signs, so were able to track traffic & applications from them.We were getting more & BETTER leads from our online ads then the signs - so an easy choice to stop using them (also time & money savings).

If I am self managing my portfolio, what do I need to check/confirm, and what easily available tools are at my disposal (online, other) to help me do this? 

There is a cumbersome way to do it on paper forms, but you should not.The only sensible way is to submit your 1099s to the IRS online, however not directly with the IRS.

If you do not find success there, there are some online companies like SpaceJoy, Decorilla, Havenly etc.

Check out other online guides available here: https://www.biggerpockets.com/guides3.

You can find online which larger institutions are buying in a specific area and try and reach out to them.

Usually you can find this online.#3 Chances are you will never buy a $500,000 property for $30,000.

I am 14 hours into the 20-hour online course offered by "RealEstateU."

You may have to do this several times for all the different tasks being done.The only labor cost not covered by this type of online inquiry is drive time from the businessto the property, to the store & back for supplies and then back to the business address.
