Age-. The general rule in the industry is that once an A/C unit reaches 10-15 years, the idea of replacing the unit is usually a much better investment than putting money into an older system. If your system is at this threshold, it's usually wise to begin expecting, not wondering, when the system will fail.
You can keep the money in the TSP after you leave your federal job to benefit from the low fees, or you can roll over the money into an IRA or a new employer's 401(k), 403(b) or 457.
Roll over your 403b into an Individual Retirement Account (IRA). Rolling over your 403b into an IRA can be a good choice because it gives you more control over your investment options, tends to have lower fees, and can ultimately hold funds from all of your previous work retirement accounts.
