...properties and using the money to buy houses? EG The houses purchased would be put on a set of properties without mortgages but other colors would be mortgaged to buy the houses for the first set-Do the rules of Monopoly allow this?

[Goop]

yes it seems you are haveing trouble with your love life beacase lonly men play dat game

[Sgt. Pepper the Cubs fan]

I believe you can do that.

[Cromwell]

As long as your not putting the houses on the mortgaged property you can do anything you want with the money.Hotels and houses MUST be sold before the property is mortgaged.Here's a trick I used as a kid. If you have 1 or more railroads and 1 other player has the rest. Make an agreement to split the rent 50-50 and decide who will hold all the railroads. That way you both make a lot more money.In real life that would be called a merger.

Yes, the rules explain the procedure for mortgaging but don't limit the circumstances under which you may mortgage.BTW, Cromwell made a post about mergers. There are no rules for mergers in the rules, therefore it is not allowed.
