". . . only thing in estate is the house valued at 150,000. . ."
Is it the case that you're actually selling the place for $150,000 . . . . or that it's simply assessed at $150,000 by your local Taxing Authority ?
Regarding the proceeds of a Sale, the Closing Agent can probably just cut you a Certified Check that you can take to a Bank and convert it to CASH.
That same Closing Agent will also be required to file appropriate reports with the Internal Revenue Service and the State of New York, as the Sale will be a Taxable Event.
