Something robust and complex enough to house all the data, but also simple enough to be able to draw the key insights as to where the sample property stands relative to the market place and how much rents have the potential to rise.

I peruse the marketplace ads occasionally.

We are not allowed to post phone numbers here, on in the market place. 

Is anyone else having issues when searching the marketplace with IPhone?

Hi Joanna, I've actually found a few by direct messaging landlords who are self-listing their rentals on the Facebook Marketplace.

Perhaps add cutting lawns and trimming bushes to your offering.In the age of Craigslist, Facebook marketplace and PayPal/Venmo/cashapp, anyone can start a side hustle pretty easily with some free ads, flyers, and a few T-shirts with your business logo.

@Mateusz Prawdzik Is absolutely right Cash is king (HML's work well too) in the Northern NJ marketplace and properties go FAST!

I'll only chime in on the "not able to sell" aspect of your post. biggerpockets.com has a market place. 

(I'm self-employed in the trades, not that I'll be doing all the work.)I joined this community thinking it would be a good place to network and bought a pro membership for the calculators and access to the marketplace.

I had enough contacts here on bigger pockets as well as in the general market place, that I sent a letter out to each one with what I was willing to pay for commission.
