Under Contract on Primary Residence with sizeable liquid capital

[Salvatore Ross]

I am currently under contract for a primary residence costing $385,000 and a locked in rate of 5.75% for 30 year fixed mortgage. I am putting in a larger down payment to lower monthly costs due to HOA fees and to have a lower DTI ratio. I will have sizeable liquid capital after the fact for a STR investment property and need opinions on the below scenarios...

*adding extra $10k lowers monthly payment by $55 each time

$110,000 (~29%) down, cash-out refi (80% LTV) = $88,000, $110,000 liquid capital

$120,000 (~31%) down, cash-out refi (80% LTV) = $96,000, $100,000 liquid capital

$130,000 (~34%) down, cash-out refi (80% LTV) = $104,000, $90,000 liquid capital

$140,000 (~37%) down, cash-out refi (80% LTV) = $112,000, $80,000 liquid capital

$150,000 (~39%) down, cash-out refi (80% LTV) = $120,000, $70,000 liquid capital
