I don't see a problem with that and would like to join one of the above mentioned or possibly a different one.So my questions are:Should I just go ahead and join the PRO version here? 

We may eventually use it for an Airbnb and might do a version of what @Jim K. suggested :) Really though, I agree with @Mitch Messer, talk the the tenant and agree to amicably conclude the lease and let them out.

If you're wanting to do that quicker though you'll have to essentially do the slow MFH version of a house flip.

Hi @James WoottonI know exactly what you are looking for.You can get a free sample cover letter/mailer template for sending cash offers by visiting the "forms" menu @ offers2owners.There is a SFR version and a land version. 

We are aware of the limitations of our current app and are in the final stages of testing before releasing the next version.

@Jason Hodges Before spending a dollar I would take the appraisals you already have and basically perform your own new version using the same exact deductions the appraiser used. 

I just put another building under contract yesterday, One the PAR contract It specifically states that the seller does NOT have the right to the appraisal, (on page 6 of 13).As @Chris K. says (my modified version) "although I'm NOT a lawyer, I did say in a Holiday Inn at one point".

If you are doing all the work on the deal you certainly could split the income more like 60% or 70% to you 40% or 30% to them or some other version of that. 

One of the bigger issues with the Independence version is mandating who you use to inspect.

Nevertheless, no matter which app it is, make sure it is user friendly and your tenants agree to use it and the company offers mobile version as well.
