Did you see the entry for 23 July 1666, involving Willem Robberts?

I did not. This is what it says approximately:

Is bij Willem Robbertsen cum sociis, kinderen en erffgenaemen van Robbert Willemsen, v[er]coft aen Jan de Monde
ende opgedragen aen Jacob Sybertsen Houthoff ende Johannes Wolffgangh Wessels [etc.]

The first and second entries concern mortgages on the property, and in the third one it is sold.

It may probably be concluded on the basis of these, that Sara Reyniers died after the 2nd and before the 3rd date.

1662
"Sara Reyniers, widow and executrix of the estate of the late Robbert Willemsen, textile worker"
1666
"Willem Robbertsen and associates, children and heirs of Robbert Willemsen"
