There is no requirement to disclose to a future buyer except if you are still in the redemption period

The value can vary based on your goals.There's the appraisal value and there's how much you, or other buyers, are willing to pay for it. 

From my understanding you can probably expect the buyer to ask to sell at the appraisal price

You close on the property yourself..by now you should have a feel for the game, know how to get sweet deals for the low low and more importantly know how to calculate repairs...yup..close on it yourself...no end buyer no assignments..that 40k profit is all yours..... hire a contracting company or if your a hands-on guy...

For example, an FHA requires only 3.5% down, but the dirty little secret is that buyers can receive up to 6% in seller concessions, and add to that another 4.5% from down payment assistance programs. 

What about mobile homes sold as an automobile with the title?

Do I have federal liens, city liens, etc that the buyer is responsible for paying.  

Then she and I renovate the house and sell in march-April next year when the school district buyers heat up? 

My vision is also to turn the worst street into the best and this property is strategic in this plan.So at the end of the day, its a win win for me, my buyer and the revitalization of North Adams.  

My personal big mistakes have been - buying home with converted garage and only car port (buyers here in So Cal, especially the guys, want/need a garage), bought a house with 55 stairs from street to front door - never again, and largest financial mistake was not going with my gut and chose to go with a new agent to list a multi million dollar property rather than my proven agent or myself.
