Loan Programs Available on $100,000 Income
Conventional 80/20
20% down eliminates PMI entirely. On a $350K home that's $70,000 down — the affordability sweet spot for this income.
Conventional with PMI
10% down (~$35K) with PMI (~$100–140/mo) until you reach 80% LTV — typically 6–9 years.
FHA Loan
Still an option but most $100K earners benefit from conventional pricing once credit is strong (720+).
