For 2024, I will have a significantly higher W-2 income (600k) due to unplanned stock option income (company I work for was purchased). 

You can move on from there and purchase a SFH if you don't like sharing a MF. 

When trying to do the deal analysis on my current property, it’s asking for the purchasing and closing costs.

And the IRS requires that all of the proceeds from the sale be used in the purchase of their new property. 

There is some purchase transactions and still private work (as I noted above). 

I would try to do 80% purchase loans on both.So 70k*80% = 56k loan amount 14k down payment + you will also have closing coststhen 120k*80 = 96k loan amount and 24k down payment + your closing costs So you will have about 32k - closing cost and loan costs for an additional investment

They cover the auctions and otc sales in a commendably detailed form, but when the sequence reaches the point of making a purchase, the instructions stop.

We are purchasing a 6 unit Apartment building in a small central Texas town. 

My apartment is identical to non-hotel-apartments in the same building, but was classified as a hotel apartment upon purchase by the owner.

Because if your house hacking I recommend you purchase a 3 bed, 2 bath, 2 car garage.
