I am currently 3 years into a 30 year mortgage at a fixed 3.25%.My options for withdrawing $50k of equity would be the following:- 15-year Home Equity Loan @5.5% which amounts to $408/mo- 30-year cash out refi at 3.375% which would add $180/mo P&I to my current mortgage payment (plus the 3 year extension) My DTI is currently 30% and my credit score fluctuates between 780-800.

Interest rates are currently fluctuating due to the ongoing pandemic and economic uncertainty, and the rates offered may also depend on different factors such as loan size, and loan term.

I think the more important question is "will the local area commissions approve the design/construction"...no permit, no carriage house...new construction prices have fluctuated recently, but my guess is you are still in the neighborhood of $150-180/ sq.ft. on something like a carriage house...

@Ethan GidcumbWhile macro trends may be helpful, I think real estate is a very regional based market where prices can fluctuate a lot when comparing state to state or even neighborhoods within states.

So I have fluctuated from telling them a few canned answers.

Other property owners may be vying for the same renters, which could lead to lower occupancy rates and less rental income.Seasonal Fluctuations: The rental income for a short-term rental property in a beach area may fluctuate seasonally, with lower demand during off-peak seasons.Maintenance Costs: Owning a short-term rental property requires regular upkeep and maintenance to keep it in top condition.

However, when you are running your numbers, I would make sure you are using a higher interest rate for post refinance than whatever you get into the deal at due to fluctuating interest rates.
