I currently own a condo, a duplex, and my personal home (half of which is rented out) all under my own name. 

My website needs to be updated but those are the homes I got from 2016 to 2019.

As for returning the deposit if there was clean up, hopefully you took photos of the condition of the home once it was vacant and have an itemized bill to present the former tenant. 

Sold to a happy first-time home buyer.

I have about 25000 saved up and I'm living at home for free how much of that should I spend on a property or save.How does someone truly manage a property "effectively" from a distance? 

Purchased all cash as a major fire damaged home & knocked almost all of it down and re-built it with new addition and rooftop deck with jet-liner views of the city!

Currently, this duplex isn't cash-flowing as I bought it as a primary home with less than 25% down.

Often lists for your area are free, or if you pay for a subscription from a local provider it probably will have more helpful detail you will want.Have fun, but leave your credit cards and checkbooks at home so you won't be tempted. 

Home buyers already had the option of not using an agent.

That is the customer and who pays, it doesn't matter who owns the home then or now.
