Keep plugging away at it. When I returned from a 2 year absence in May I had about the same Multilplier you have. Now it's up to 1329.85%.
Use your House Farm to create cash to buy KEMs and Rat Trap Trucks to get Bonuts to buy Mystery Boxes...
And don't buy into the lie about House Farms taking forever and costing too much: House farms pay for themselves.
Here's the
spreadsheet that shows how long it takes to recoup the cost of each Blue House you add to your Blue House Farm. You 'borrow' the initial cost of each house from yourself, then columns C and D show how long in either taps or days it takes to recoup the loan using the income from your entire house farm.
You'll need to copy the spreadsheet and change the bonus percentage to your own of course. My example uses the multiplier from a test town I'm running. But a quick check shows that at your Multiplier you'll never have to tap your Blue House Farm (all of them) more than 2 times to recoup the cost of the buildings.
