If the house is showing an assessed value of $280 and you close on it for $200 ***and do no renovations*** I'd say you have a pretty good case to get a tax reduction. 

A good/reliable contractor is worth their weight in gold so that you do not have to deal with these issues.

., assume fewer things are OK and be more cautious about possible issues).Besides the overall state of the market, which has taken more buyers out of the market and thus shifted more power to buyers vs. sellers, also look at that specific property, specifically its time on market and listing history.If it was listed 6 months ago, didn't sell, and was relisted 2 months ago and has already been on market 50+ days before your offer was accepted, I'd think you'd be in a stronger position to make more asks from the inspection results, than if this was the first time it was listed and it's only been 3 DOM, and especially if there were multiple offers (though sometimes those are made-up so I'd give more weight to DOM than alleged other offers).

What cash flow numbers (or rent reduction numbers) are you looking for?

I'd give the most weight to word of mouth referrals from investors you trust and online reviews (specifically Bigger Pockets references which are the easiest to verify since they're linked to the reviewers profile).

Tenant now requests a reduction citing a slow down in business.

The buyers could have asked for a price reduction and/or incentives that the sellers didn't agree to.

@Zach Wain and @Joe Splitrock, I am wondering if this change actually causes reductions in underwriting, so that instead of lowering the number of Rental/2nd home mortgages, the lenders start pushing through lower quality owner-occupant loans to raise total mortgage volume, thereby allowing for continued processing of 2nd home/Rental mortgages

The result was a 75% reduction in number of workers managed, a flattening of the organizational chart, a workweek cut by more than half, and very little change to bottom line profitability.   

I advise my clients to never waive an inspection contingency (in an FHA loan, most likely the bank will either require one or conduct their own) - HOWEVER, your agent could position the inspection contingency as a means for "peace of mind" and state that you won't come back to the seller for price reductions if anything pops up.
