From a tax perspective, you'll want to take what you paid for the property plus calculate the improvements you made to the property during your time of ownership.

Property taxes-  normally paid in a delayed basis.  

i have people in my network who find deals; they get paid if I buy them; i diligence them; and then my PMs manage them.i didn't look at your profile, but do you already own rentals? 

They only get paid 1% of the credit lines they get for you successfully.

.: I haven't passed this past legal review so for what its worth: Part of my standard requirements for everyone include income is at least 3X rent, minimum credit score, say 640, Clean record and no evictions as well as deposit is paid in full at signing of lease and 1st month rent is paid in full prior to handing over the keys.

It's easy for me to get lost in the grind or to focus on goals instead of progress so I'm glad that I took this moment to remember where it all started and that was with a gamble on this one property that has paid off ever since.

I'm still in the process of finding an alternative solution but I thought I'd leave this here as a warning for others looking to make a decision.For reference, I'll just post their email response to me here:As we review your inquiry, we would like to remind you of the following key points from our Terms of Use:In no instance shall ShinePay be liable for any of the following:"Lost revenue from service interruptions.Lost revenue stemming from delays, malfunctions of any product.unauthorized gains access to your account or due to shared passwords or if your password is hacked.Destruction to properly, places, or personal injury resulting from the installation, misinstalling, or misuse of any product.Lost revenue from entering the wrong account number for ACH or other bank transfer or money transfers or due to any delay in receiving funds.Damage to your structure, machines or car resulting from use or installation of our products.Any funds collected that are paid to a person that does not own the property.Any harm from defeating the lock and technology that controls the lock to a device.Failure to properly service any product or machine."

Loopnet has some comp information, but requires a paid (and not cheap) account to see it.Commercial properties are generally valued based on income, not comps per se. 

I've found this to be super helpful: When someone inquires about the property Thank them and Send them the pre-requirements (Income, credit, no evictions) and ask if they meet them.

On your tax return you would report the proceeds, subtract costs and proceeds paid to seller, then the remaining profit would be your flat fee.
