A lower priced entry level house will need less of a price reduction than a high end house in a high end town.  

If it appraises for less, you could try to come back to the seller for a reduction but it might be hard depending on the type of property.

It will tell you how long it has been on the market, what it sold for last, price reductions, etc.

We gave him a cash offer, but well below asking to "contrast" it with our seller financed offer.It won't always work but look for properties which have been on the market a long time without reductions - that is often a signal that the seller is stuck on a price...

Or should I try and negotiate a price reduction from work they are doing? 

The winter market has been slow and we have been on the market for over 2 months with a significant price reduction. 

All convert to long term housing with appreciable rent reduction in west coast.

Hello Darrel,I am active duty myself and I currently have a property, which I acquired with a VA loan, that is being rented.I have also refinanced this same loan, which resulted in a reduction in my interest rate (4.75% to 3.75%).After living in the home for about three years I received orders and consequently hired a property manager to handle my soon to be rental.

They then come to you down the line owning it and ask for a rent reduction or they move to somewhere else paying cheaper rent.

I'm sorry to hear you are having issues, hopefully you can fight it, but in my experience on the lending and investing side, the appraiser won't budge unless they made a trivial mistake (forgot to take into consideration major highway dividing lines, incorrect square footage on records, fat fingering an address, etc.)
