How the "Ramirez Family" Maximized BAH and TSP to Net $280k in 7 Years
An E-6 family's playbook for military-specific benefits, house hacking, and TSP.
Calculators used in this story
The Setup
Sgt. Ramirez promoted to E-6 in late 2018 and transferred to Joint Base Lewis-McChord in 2019. His total compensation at the time included $3,820/month in base pay, $2,106/month in BAH (Basic Allowance for Housing, tax-free), $402/month in BAS (food allowance, tax-free), and various smaller entitlements. His spouse left a part-time job in the move and took 18 months off before picking up remote work at $28,000/year. The family of four decided early they would live on base pay alone and treat BAH as investment/housing capital.
The VA Loan House Hack
Rather than live in base housing (which takes the entire BAH as rent) or rent off-post, the Ramirez family used a VA loan with zero down to purchase a $340,000 four-bedroom duplex in Lakewood. They lived in the three-bedroom side and rented the one-bedroom side for $1,150/month. Their PITI on the duplex ran $2,280/month. BAH ($2,106) plus rental income ($1,150) covered $3,256 of housing cost — $976/month above mortgage, which went to principal prepayment and a house maintenance fund. They ran the scenarios through CalcFi's house hacking calculator to validate the math before closing.
TSP Strategy
Military members have access to the Thrift Savings Plan (TSP), the federal government's 401(k) equivalent. In the Blended Retirement System (BRS), service members receive 1% automatic contribution plus up to 4% match — so 5% of base pay is effectively free money if you contribute 5%. Ramirez contributed 15% to Roth TSP from day one. At his 2019 base pay that was $573/month. He used the C Fund (S&P 500 index) and S Fund (small cap) at 80/20 split. Deployed income was tax-free, so deployment-period TSP contributions grew the tax-free Roth basis dramatically. He also maxed a Roth IRA at $6,000/year (rising to $7,000), and his spouse did the same once she resumed work.
Combat Zone Tax Exclusion
Ramirez deployed twice in the seven-year window: a nine-month rotation in 2021 and a six-month rotation in 2024. While in a designated combat zone, his entire base pay was federal tax-free. He used those tax-free months to max his TSP annual elective deferral (including the special limit extension for combat-zone contributions), dumping as much as $21,000 into Roth TSP across the two deployments that would otherwise have been taxed at roughly 12-15% marginal. Pure tax-free growth forever.
SCRA and Interest Rate Reduction
Under the Servicemembers Civil Relief Act, any loan taken out before entering active duty (or a call-up) can have its interest rate capped at 6% while on active duty. When Ramirez was on orders in 2020, his spouse's pre-service private student loans at 7.4% were reduced to 6% via SCRA — saving roughly $480 over the deployment period. Minor, but worth knowing. More materially: the VA loan came with no PMI, saving approximately $190/month versus a conventional 0% down loan if that had even been possible.
Year-By-Year Net Worth
Starting net worth end of 2018: -$4,800 (student loans, small credit card). End 2019: $18,000. End 2020: $44,000 (deployment income windfall). End 2021: $74,000. End 2022: $102,000 (market drawdown softened by continued contributions and principal paydown). End 2023: $164,000 (strong market recovery). End 2024: $221,000 (second deployment). End 2025: $281,000. Breakdown at end of 2025: $156,000 TSP, $61,000 in Roth IRAs, $58,000 in home equity (mortgage down from $340k to about $289k on a home now worth $376k), $6,000 emergency fund.
Mistakes They Made
Two regrets. First, Ramirez did not start TSP contributions until three months into active duty — he missed the match for those three months, costing roughly $650 plus compound growth over a 30-year horizon (about $6,000 of lost future value). Second, they bought a slightly too-expensive used minivan in 2021, financing $28,000 at 5.9% when they could have spent $18,000 cash on something older but reliable. They paid the loan off in 2023 but lost approximately $2,400 in interest plus opportunity cost.
What They Tell Other Military Families
Three non-negotiables: (1) contribute at least 5% to TSP from paycheck one to capture the full match. (2) Use your VA loan at least once; zero down plus no PMI is an advantage no civilian has. (3) Treat BAH as a separate housing envelope — if you can find a way to generate rental income against it, every dollar above mortgage payment is essentially free wealth. Also: read about SCRA, the combat zone tax exclusion, and military OneSource before you need them, not after.
Frequently Asked Questions
Is BAH taxable?
No. BAH, BAS, and most other military allowances are federal and state tax-free, making each allowance dollar worth roughly 15-25% more than equivalent taxable income.
Should I use Roth TSP or Traditional TSP?
Roth TSP usually wins for junior enlisted in the 10-12% bracket. Traditional often wins for senior officers in the 22%+ bracket. Many service members split 50/50.
Can I use my VA loan more than once?
Yes. VA loan entitlement can be restored after selling a home or paying off the loan. Many military families use the VA loan at multiple duty stations.
