If not, I would recommend purchasing as it is worth it compared to a large investment you are about to make...

We recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

I usually use key check because it’s cheaper for tenants ($35) compared to avail which is $50.

I have reached out to a few other lenders to compare.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

That being said the only way these low cost providers could protect themselves would be to write their programs in such a way that the benefit their work provides is so low compared to the reality of what is allowable that there isn't any chance of overstatement of depreciation, which means it would be understated and you're leaving money on the table. 

The issue with using comps on any type of software, especially propstream or dealmachine is that they tend to use an "estimated value" of the homes that they are using for comps, not actually comparing to what has sold recently in the area or what is currently listed, not accounting for DOM (day on market) or other market shifts that play into realistic valuation of a property.

You have to consider the numbers, then compare that to reality.

I own and manage STR's in this area and I can't find another market to beat it when comparing cash-flow.

On a side note: having read legalzoom documents and comparing them documents written by attorneys within the state, I can tell you there is a reason they are cheap.
