 Prixinen Haus, House No. 300, today Arcas 3 
Through the marriage of Joseph Köhl with Barbara Prixin, part of the house came into the possession of the Köhls. Bernhard Köhl lived here with his parents from 1646 and his parents lived in this house until their death in 1670/71. After that Bernhard's son, the future pastor Bernhart Köhl, lived in this house. The house then became the property of Dr. Joseph Köhl. This property probably went to a community of heirs after his death in 1750.
 Obere Reichsgasse, House No. 179, heute Paradiesgasse 19
On September 25, 1650, creditors of the deceased Chur citizen Joseph Köhl sold his house and stable on the upper Reichsgasse Chur for 1300 gulden to Bernhard Köhl, who was only 26 years old. One of the creditors was Valentin Davaser, who had bought the house of the deceased tanner Gili Köhl in 1620. It is not known whether Bernhard and his family moved into this house in 1650.
On December 16, 1656, Georg Reidt, citizen and old mayor of Chur, sold to Bernhard Köhl a stable and barn located near the smithy guild for 350 gulden. Bernhard thus increased his property on Reichsgasse.
In November 1690, Hans Lutzi Pedron and his sister Ursula Pedron sold to the mayor Bernhard Köhl the house (5) with stable inherited from their grandfather Klaas Hassler and their father Lutzi Pedron, respectively, located on the upper Reichgasse in Chur, for the price of 1,153 gulden. Signed by the Chur chancellor Johann Baptista Bawier.
"The dwelling house together with the rear vaulted corridor and stables attached to it, bordering towards the morning on Gevatter Daniel Sißen Haus and Funfer Caspar Paravicinen Haus together with stables and common alley next to the Paradies, at noon on the common Reichsgasse and at midnight on löbliche Schmiedzunft Hösli." This is how the location of the property is described.
In the entry in his will of 1690, he boasts that he "has his residential house together with the Lutzi Pedronen house purchased for it, which is a threefold delicious and beautiful house, because I have set my new noble coat of arms in stone". At the latest at this time he lived with his family in this house. This coat of arms is no longer attached to the building today.
His sons are not listed as owners of the property after 1730. Presumably Bernhard bequeathed his residence to his daughters.
 St. Martinsplatz, House No. 172, heute St. Martinsplatz 4
In front of Martinsplatz Bernhard owned half a dwelling with two stores and accessories (4) above Stephan Reidten's house. Presumably, his son Peter Köhl lived in this apartment from 1680, as he also worked in his father's store. Also his daughter Emeritha may have lived here after the early death of her husband. According to the entry in the tax books in 1726 and 1733, the property was owned by 4 families:
Winterberg, House No. 470, today Winterbergweg 1
Before 1672 he bought a house located in the Winterberg, with stable, garden, well and associated vineyard of Luzi Duffert blessed. The house was then sold again in 1761 by grandson head guild master Bernhard Köhl.
Plessurgut, Nr. 370, heute Industriestrasse 18 und 20
Around 1684, Mayor Bernhard Köhl bought an estate on the Plessur. This estate consisted of meadows, fields, a tree garden and a house.
Bernhard bequeathed this land to his son, Bernhart Köhl (1661-†~1727) - the pastor. He in turn bequeathed it to his son, Bernhard von Köhl (1693-†1762) - captain & head guildmaster. After his death in 1762 it was inherited by his son, Christian Köhl (1755-†1807) - constable of Chur. His heirs fought over the inheritance and so in 1816, after having been in the possession of the Köhl family for 134 years, the Köhl's Plessurgut was sold to Jakob Marx.
In 1857 Sebastian von Köhl, (1793-†1857) - colonel and city bailiff bought back the Köhlsche Plessurgut shortly before his death. The estate was now to remain in the possession of the Köhl family for another 35 years. After the death of Simeon Arnold Bernhard Köhl, the last nobleman of Köhl in Chur, his widow, Hulda Leuch sold the Köhlsche Plessurgut in 1892.
