I'm looking to buy a house hack and am currently in the process of running numbers. 

My current mortgage is 3.6% on $112,500.

I currently own a duplex and am finishing the rehab on it.

Here’s what typically happens when investment loans go 90 days into default1- loan is placed in “non per forming category”2- non payment information sent to credit bureaus, and borrower shows “90 days late”3- Fair Issac credit score drops 150+ points4- credit requests get denied, credit available is at rates 5 points higher than before5- notes are accelerated by lenders6- legal fees are added to principal balance owed7- the lender accelerates the loan8- interest rate is increased from the current Rae to the “default” rate9- late fees are added to the principal balance 

There's two I currently go to in Austin, TX: Every Wednesday at 12PM at the Jalisco's Bar & Restaurant in Buda, TX, and the North Austin meet up in The Brass tap bar near Natural Grocers on North Lamar.

You can definitely work out something with the seller that makes your offer contingent on the sale of your current apartment. 

I think some of the newer construction is sitting well above current market value and could be in jeopardy if the market adjusts or the economy continues to fluctuate with inflation.Depending on where you live and what your comfort level is there are several other states that can offer a better cash flow for a similar price range.  

I'm currently doing both.

That is true, but is it the best in this current environment?

Seems you’re looking for appreciation with steady income and that’s a good approach in this current market state.
