@Ria S.
You paid $150k for a property and the PITI (including HOA) is $950, current value is $310k and you owe $140k (rate of 2.4%), so you have $170k in equity. Monthly Airbnb rent is $4500 (expenses of 20% of rent, these vary a lot depending on the property, but this is a good starting point), so Net Rent after expenses is $3600.
This means you are getting $2650 of cash flow; $31,800 annually
Plus let's say your monthly principal portion of your PITI is $275; $3300 annually
Plus let’s say your property appreciates 3% on $310k value that's $775 monthly; $9300 annually
Total that’s a $44,400 return on your $170k (26% ROE)
Lets look at the cash out refi on the property with 75% LTV.
Home is worth $310k and you owe $232k (Rate of 6.7%). PITI is $1900, Principal Paydown is $200 and Rent is $4500 ($3600 after expenses)
Cash Flow $1700; $20,400 annually
Principal Paydown $200; $2400 annually
Appreciation $775; $9300 annually
Total that's a $32,100 return on $78k (41% ROE)
In this example you would cash out about $80-85k after closing costs, your return is about $12k less per year, so the question is can you make more than $12k per year with that money with a new investment? I would say probably yes if you can repeat this same investment or something similar to it.
I hope this helps, good luck!
