Am I being unreasonable?

I've found that some inspectors can be beyond unreasonable with structural concerns.

I'm sure you are glad to have all the hurdles of The Grand Prarie and Mesqute acquisitions behind you.  

To dig deeper, what are the return-risk hurdles you are seeking?

I think unless you are in an incredibly hot market offering a home for lower then the competition this many hurdles will lead to longer vacancy.I am not opposed to hurdles to screen out the unmotivated ones but this is a large amount of hoops that will definitely lead to decreased demand.It is a trade off.Your life is easier & you have much more timeButYour rentals will be empty longer.

Then I reminded him if he finds it unreasonable the clause in the lease contract states he can terminate the contract as long as 45 day notice is given.

I'm not a lawyer, so no legal advice, but my understanding is unless you can show where it is an unreasonable burden for you to allow this (and possibly losing insurance would be that burden but I don't know), then you cannot discriminate against a service dog, no matter what breed.  

I think this difficult margin hurdle exists because of the high list price.

Most short sales fail because the listing agent puts an unreasonably high price on the property, and nobody makes an offer.

2 - If you have no clue what you're looking for and where to find it, I think you're being a bit unreasonable in thinking you'll be able to close on a home within a month.
