@Samuel W., most DSCR programs limit you at a 75% LTV. Therefore, you can take out about $240,000. However, after factoring in the renovation expenses, closing costs, discount point, and pre-payment penalty, it will likely be closer to $160,000 that you get out.
Assuming a 7% rate, your monthly payment would increase by about $1,600.
Which is more important to you $1,600 per month in cash flow or $160,000 to reinvest somewhere else?
I love getting paid for doing refinances as much as the next guy but sometimes they do not make sense.
RSUs cannot be considered as income for conventional financing so it will be tough finding better options than a DSCR.
You could try doing a net rent loan where they underwrite your file as if it were conventional but the rental income is calculated based on the lease agreement or AirBnB payouts for STRs.
However, you typically need 12 months of rental history to use this product.
The advantage of this is that the rate is about .5% lower than DSCR.
If you want to use this program and avoid the prepayment penalty, waiting a year could be a good option.
Hope this helps! Let me know if I can be of any assistance.
