I don't think it's unreasonable to think he can do better than 45% gross expenses if he can truly get these numbers.

Am I being unreasonable?

My opinion is that, unless he is looking for absolute dumps to rehab, he is being a bit unreasonable. 

I don't think Rob asked for anything unreasonable, but we will see what the sellers think and come back to us with what they are willing to remedy and what they aren't willing to budge on.The inspection/due diligence period ends on this upcoming Monday so it gives us some time.

Not an unreasonable rate for a secure investment that does not require the time, trouble and risk of buying a rental house instead.But that being said, I would of course rather get 20-30% return instead.  

Do my offer is the only one being negotiated until i cant come up to the banks unreasonable price.

There are laws in place regarding loud and unreasonable noise, and intentionally disturbing another person’s peace.

Come noon yesterday, the sellers still weren't out of the house and were blaming us for being unreasonable and forcing them to move (they wanted the $20K AND the house apparently :).We finally told them, "Look, if you want to get this closed today, we'll give you an extra 24 hours to get your stuff out of the house."

Not many, but they may when you want to sell and your title insurance will not cover that without a proper survey you may have bought a rental or incurr legal fees trying to get that garage moved or exempted.I don't think 30 days of studying before you leap is unreasonable or will keep anyone from eating that much later.

I would look at when the ratio of rent vs. price becomes really unreasonable.
