Rental property, does higher down payment make sense

[John Peppard]

Looking to purchase a rental property for $330k, leases are already in place for the following year and rent roll is $3200 per month. At 25% down I’m looking at roughly $2300 for principal, insurance, and taxes per month on a 30 year loan at 7.6%. What are some thoughts on putting say 30% down to increase cash flow a little bit and pay less interest over the life of the loan ? This will be the 3rd rental property in my portfolio. 
with the interest rates being so high I feel Iike a higher down payment could be a good idea over the long run, but I’d like to hear some ides on this, thanks in advance !
