I'd like to not "find out the hard way" if one of these sites are not a good match for me.The ones I'm considering are Propstream, Property Radar, ListSource, and PropwireSomething to note, I am looking to return to doing some wholesale deals, using criteria such as absentee owner, out of state owner, tax delinquent, vacant, liens, and pre-foreclosure..

You must use a PMS and for the software to work you'll need to own the listings, which means you'll need to also collect all the funds, so owners' rents don't get deposited in the wrong account (Yes, Airbnb makes that mistake all the time!!).

I suspect all security deposit need to go to the owner or a new PM..

Offer to give them their full deposit in cash on move-out day, if they leave the place clean and empty, etc.  

Then as you build your portfolio look to hire a new Tax Accountant or CPA to match your growing needs.

We have to order six months ahead from our Mennonite source and put a deposit down

Quote from @Stetson Oates: The vast majority of disputes are over security deposits and the most a landlord could lose is 3x the deposit amount.Slip-and-fall or other major lawsuits almost never happen.

I have done small things like switch from glass wine cups to acryliic ones that look like glass and take a damage deposit of $250 that helps mitigate small things breaking that are over $50.

Arthur - As I mentioned to another poster above, please call the SEC and give them all the details about your interactions with RADD, about company insiders looting their investment capital in the bright light of day through the use of multi million dollar promissory notes between the Mendenhall family and the company, that they've been paying their sales force in Ontario and Pennsylvania via 1099 and that a review of the real estate assets in Philadelphia newspaper and Texas that is subject to foreclosure litigation does not match up to what they should have been purchasing based upon what is described in their sales presentations.
