Everyone's circumstances are different, so maybe it makes sense for you to borrow against the 401k, but I just think it is important that folks are fully educated on all factors before making that decision. 

Why we build the same floorplan over and over again:1) Easier for Trades and Faster Build Times: Our trades have been working on the same layouts repeatedly, so they have become more efficient.2) Less Mental Space for Decisions: We don’t spend too much time deciding on which floorplan to build, we focus our time on growing the business and serving our customers.3) Best ROI based on Square Footage: The floorplan we build gives us the best return on investment.

However, investors should consider property taxes, local regulations, and neighborhood trends carefully before making decisions.

Also the interview is a big part of decision making, because most important is to have a person who is responsible and keeps your property clean.We don't look at bank statements, but we do want to see the last pay stub before we sign the lease and make sure the employer and the amount matches the application.

I bought my first house hack while having student loans it was the best decision.

What else would you consider before making this keep/sell decision?

Good LuckTypically multifamily is 5 units or more and Single Families are 1-4 units, so I was confused, so thanks for the clarification  Actually, that part is only half true because there are additional criteria that need to be considered to be multifamily vs SFR, such as separate utilities, heating systems, how they are attached to one another (Vertically vs horizontally), etcan easy way to differentiate and communicate is to call it multifamily if it has more than 5 units. and Single family for 1-4 units or call it how it is duplexI own several duplexes that are considered single-family homes by the city.In the end, it is your decision on how to use it

The decision becomes so much easier if the exchange rate is close to 0.8-0.85 which where it has traded traditionally.

The deal of a lifetime or a deal with incorrect numbers or problems that aren't being addressed. 

This will cause more supply and less demand = lower prices.Of course, none of us have a crystal ball, but that is just my two cents for economics 101 :)This is incorrect in my experience.
