any actual detailed insight to how this works would be greatly appreciated.

@Steve Oswald what cash flow target are you using to estimate the 160k?

The [OA] and supporting docs I received through the company who set it up, were very extensive, had great detail, etc. 

They are paid by the sole owner through their quarterly estimated payments and annual tax returns.From the IRS website:An individual owner of a single-member LLC that operates a trade or business is subject to the tax on net earnings from self employment in the same manner as a sole proprietorship.

Feel free to PM me or simply look up my profile for more details.  

My question however is, what website to trust for the most accurate estimate on property taxes?

@Shasky CharlesBlue ocean opportunities in commercial real estate by Cherif Medawar This is an amazing book that is available on Amazon for $2.99 Cherif Medawar is an experienced investor, teacher and a real estate fund manager so he has a lot of experience and his book details some great strategies and concepts - I could not put it down and have recommended to many people who enjoyed it and used its business models

It has no bearing on what price the lender will agree to.Points to know....First, use an Experienced short sale Buyers agent....there are just to many things to look out for in a short sale.Find out how many mtgs/liens are on the property....many times a buyer has to pony up extra money to satisfy a junior lien holder, above what the first lender will offer them.Assuming all paperwork’s has been submitted, expect 30-60 days for bank to do a bpo and accept=counter your offer.Submit a gc repair estimate with your purchase agreement.If the comps are $200k, you’ll never get it for $80k unless there is a serious documental $100k problem with the property.

I'd be cautious of generous estimates, though.

Estimated property value in our primary residence is $275K.
