SELLING PROPERN:
Unimproved properties, railroads and util~ties
(but not buildings) may be sold to any player as a private transaction
for any amount the owner can get; however, no property can be sold to
-
another player if buildings are standing on any properties of that color-
group. Any buildings so located must be sold back to the Bank before
the owner can sell any property of that color-group.
Houses and hotels may be sold back to the Bank at any time for one-
half the price paid for them.
All houses on one color-group must be sold one by one, evenly, in
reverse of the manner in which they were erected.
All hotels on one color-group may be sold at once, or they may be
sold one house at a time (one hotel equals five houses), evenly, in
reverse of the manner in which they were erected.
MORTGAGES:
Unimproved properties can be mortgaged through the
Bank at any time. Before an improved property can be mortgaged, all
the buildings on all the properties of its color-group must be sold back
to the Bank at half price. The mortgage value is printed on each Title
Deed card.
No rent can be collected on mortgaged properties or utilities,
but rent can be collected on unmortgaged properties in the
same group.
In order to lift the mortgage, the owner must pay the Bank the
amount of the mortgage plus 10% interest. When all the propert~es of
a color-group are no longer mortgaged, the owner may begin to buy
back houses at full price.
The player who mortgages property retains possession of it and
no other player may secure it by lifting the mortgage from the Bank.
However, the owner may sell this mortgaged property to another player
at any agreed price. If you are the new owner, you may lift the mortgage
at once if you wish by paying off the mortgage plus
10% interest to the Bank. If the mortgage is not lifted
at once, you must pay the Bank
10%
interest when
you buy the property and if you lift the
mortgage later you must pay the Bank
an additional 10% interest as well
as the amount of the mortgage.
