I'm not one to plug my business and there is enough good, bad and ugly online for all to see.You will find many "real world" reviews on both Ohio Cashflow and Oz Realty via a Google search.Not perfect by any means and we make mistakes.Honest mistakes that we do our best to rectify.Standing the test of time in a real estate niche called turnkey that has been scared by many shady operators speaks for itself IMO.I will say this, investors buying sub $100,000 properties and only owning 1 or 2 and expecting miracles are usually unsatisfied.Sub $100,000 requires volume to work and for a decent long term return to be realized.Our price points are $70,000 - $100,000 and rent's are from $750 - $1,100pm2bed, 1bath and 3 bed, 1 bath is our bread and butter.Sometimes 4 bed, 1 bath and rarely 4 bed, 2 bath or 3 bed, 2 bath.The odd duplex from time to time and the odd 4 unit or 6 unit but those are rare.B class areas mostly.Sometimes B- and C class on occasion which we will stress clearly in any deal pro-forma along with the pro's and con's.Also, those that get their panties in a tangle and decide to leave the wing of Ohio Cashflow, we can't help much anymore as it get's messy and muddy so we have to politely bow out from any continued engagement. 

Facebook and Google already know everything about someone, why not try running targeted ads?  

And some unicorn backed by Paypal and Google powered by Nvidia GPU would create docusign-AI+Advisor mode that replaced the entire need of buyer  agent completely. 

Before we built our own solution, we were making do with a shared Google sheet.

Quote from @Tricia O'Brien: If you learn to use a search engine, you can find about anything.Go to Google, type in the name of the document/form you are looking for, and the state it applies to.

I just did a few minutes Google searching and found this.

Once you have a substantial sample size, itemize them on a Google sheet form and compare the Price, Price per square foot, Lot size, price per bedroom, etc.

Sounds like you're at your wits end here so it may be like ripping off a band aid, just getting rid of all of them at once.

You could easily manage a significant volume through a free Google Voice number and an email address.Considering that most residents lean towards email and text rather than phone calls, you can periodically check those messages or any voicemails left for you.As your business expands, you might want to consider implementing an efficient property management software.
