I wish my plumber had done what I asked but also seems very unreasonable for company to keep half my purchase for "set up bs fees".   

Your property may, or may not pass that inspection (I have heard may stories where section 8 inspections were VERY stringent, to the point of being unreasonable).  

Don't knowingly do something unreasonable.

It is not like those are unreasonable.

It is a lot of money, but I don't think its unreasonable considering the price of the property. 

Tenant shall not keep on the Premises any item of a dangerous, flammable or explosive character that might unreasonably increase the danger of fire or explosion on the Premises or that might be considered hazardous or extra hazardous by any responsible insurance company.13.

Taxes increase every year but that kind of jump seems un reasonable. 

If the owner had been reasonable and the tenant did this, I would not find this quite so hilarious, but owner sounds like a pretty unreasonable guy who won't listen to basic facts, so I guess he gets what he deserves.

When you factor in all these things, it's not unreasonable to think that your maximum offer may have changed over time.Given that the sellers would complain if you were willing to pay more, they shouldn't complain that you're willing to pay less (though they will :), and the fact that you have some additional negotiating leverage isn't something you need to apologize for -- the seller's could have anticipated that situation and done something to avoid it earlier (like sell to you at $280K), but they were holding out for better.

He's not usually this unreasonable, but I think the visions of big dollar signs have taken him over.
