Recently submitting an appeal for my house, I was told that there is a rick that an appeal could lead to a higher assessment if it's found your is undervalued; typically uncommon in Cook County. https://taxbacknow.com/

Is there a tool or software that can do this?

@Michael Csrnko1) Make sure to use a pricing software like price labs or wheelhouse to have competitive pricing. 2) Don't always give refunds or credits to guests when they complain to get a 5 star review.

Submit Deed of Trust - OR - Mortgage (since it's Oklahoma) along with Purchase Agreement?

Next year submit a new increase. 

Hey Carlo, a seasoned PM or any PMC (should) come ready to manage your property with their own software (like RentRedi) but if you chose to provide said software, that would be up to you!

Update- After dealing with a couple different realtors and submitting offers.

I have a business mentor, a technical mentor (for using software programs most effectively), and one on one support for SEO. 

I've researching which software application to use to help me grow my SFR portfolio.

I agree with a lot of the advice already given (i.e. legal lease agreement, maintenance team, etc) i would HIGHLY recommend utilizing a property management software to run everything through.
