Mortgage Advice - Amortization & Loan Types

[Austin Phelps]

We're planning on getting pre-approved for a loan here in the next 5 months. We're both disabled veterans, so we have the VA loan available to us with reduced fees. We're trying to decide if we should do 3% down and do a 20 year fixed or go with a 10% down on 30 year fixed. We'll live in the house for 12-18 months and then COR to start our BRRRR journey. We're currently set at putting 3%-8% down on a 30 year fixed and paying the monthly payment as if it were a 20 year fixed. We've never done this before, so please poke holes or offer suggestions. Thanks in advance for anyone taking their time to reply!

Additional note: We're looking at $350k properties and looking to put ~$50k of renovations into it.
