I have paid my ftb advance early three times. (Am actually doing it this week cos we have rego and license renewal due within two weeks right on dds birthday!). Ftb can be paid out early and advanced again immediately provided you meet normal criteria (no debts etc). The others can't. Ftb is the only one. As long as you have paid it all back you should be fine.

On due for ftb thurs. it gets processed tomorrow so I can apply again weds and have money in account Friday...
