Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

Have a 1960s 30 unit single story motel where we are coming up on some end of life issues: the cast iron plumbing is disintegrating underneath bathrooms, radiators are starting to leak, electrical is in poor condition, and just today, discovered significant termite damage affecting multiple rooms.

get a copy of the agreement used by agents in your area and merge it with wholesaling agreements you can discover on Jerry Norton's site.

If there were a serious insurance claim, god forbid human injury or loss of life, and they do the same research discovering the non-conforming construction of habitable space, why would they bail you out?

@Zehua Zhou, You have a flawed setup.

When the tenants moved out, he discovered they had utterly trashed the place and the cost to bring it back to market standard (and thereby get a more desirable tenant) was beyond him. 

Ok but I am not talking about by defaulting, the scenario is if the Due-on_sale Clause is triggered because they discovered the sale.  

The other "investor" flogging this says this is a "brand new company" and another fanatic said he uses it even though he discovered its someone elses product that just got another name slapped on.

One thing I discovered recently is they make heavy use of the Schedule E from your tax return, so if you clean up your Schedule E (eg by minimizing repairs and maximizing CapEx and accelerated depreciation), you should be in much better shape.
