However I may just send the wholesaler this end buyer in hopes they will provide me a finder's fee.If not, no big deal and I move on knowing this is their method and we won't work out.

That method is cumbersome, time-consuming and bogggles my mind.

This perfectly highlights one of the top 3 FILURE methods of thinking; the "oh no, I better be careful to have to to owe/pay too much in tax's" lie. 

I think I will try this method.

My three main methods that I use currently are rentometer, comps from my realtor, and apartments.com.

This method will be less expensive however you will need to provide more training/guidance and set clear expectations on what you are looking to achieve.

Given the nature of your question I am guessing that you have some friends or acquaintances who wish to pool capital to invest together in a syndication opportunity and they're relying on your expertise in some fashion to decide if the deal is a good one. 

This is my first time doing the brrrr method but i own a triplex. 

As for urine smell, I recommend Nature’s Miracle Urine Destroyer.

Most BRRRR method properties will be around 200% return.
