Have one quick question. Will be buying new home and renting current. Next year will have to repay the First Time Home Buyer loan ($5000). Looking for ways to lower my taxable income for next year. Currently only contributing 5% towards TSP. Was thinking about contributing more. Questions is, should I do it towards regular TSP of Roth? Will also go to zero dependents in order to take a lesser hit come next tax year. Any advise will help. Thanks in advance.
