I would likely pass on reviewing since what they did was not egregious. 

If this is for personal use then I'm not sure I'd entertain this idea.

DO NOT GO SIDE TO SIDE against the grain or swirl..... one full pass going with the grain, then move over and do another full pass...full length.

My worry is that the property might fall into probate or tax auction once he passes and someone who knows someone will get the deal under contract before it reaches public offering.There is a real estate agent in the area that gets about 85% of all the listings in the micro-market, so she is farming these properties constantly. 

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

This bill that would hugely increase property taxes for STRs (after they just took a massive jump for all residential properties) just passed committee and is headed for the legislature. 

It's worth doing a bit of research if possible, with former landlords, or search any records of cases the tenants may have brought to court in the pass. 

I pass these on to my clients looking to get a discount as most stuff on the MLS is overpriced. 

Ultimately I don't think there is a way...most small rentals operate in a manner where they pass through to your personal return.

I still have them complete my full application separately, and for those who do the showing and like it after passing my initial screening, then I run a background/credit check of my own.
