You are not being unreasonable.Your agent should accomodate to you and not the other way around.Repairs, if approved by you, should be done however YOU want them done, so, you can choose who makes the repairs, time, day, etc., unless you agreed to something different on the contract. And most importantly, you should wait until the bank has approved the deal, there is no sense in starting to do repairs if the bank has not approved it.Good luck!
Ask a realtor in your area, he/she will be able to give you a comparative market analysis; another option is to pay for an appraisal.
This link tells you what Zillow says about the way the zestimate is determined: http://www.zillow.com/wikipages/What-is-a-Zestimate/
One way to do it is to go to: www.postlets.com and fill out the information for sale and/or rent. If you have post to zillow, it will post within a few days
When you are ready is a good time to sell.More houses are in the market during spring, that means more houses that buyers need to sort through.
What does the tax record for the property say?
You have to edit your profile and add the areas you service.
You have to disclose the correct information to the loan officer. If the documentation is reviewed at a later date and someone finds it is not true, you could be subject to a fine!
It depends on your state. You'll need to check out the local rules for property managers.
