Walkthroughs are never detailed enough to be final (ie often tenants have lower disconnected and discover broken appliances later.) 

if your loan is 154k  then this prop probably appraised for loan purposes at 200k or so. and that price point is usually in a decent area or street..

I know of a lender that offers a 0% down, owner-occupant conventional loan that is a fantastic option for househacking.

 @Raif Jochim without knowing details of each loan, I would almost always choose the primary home.

The way I'm looking at it, if my spouse and I only do employer matching for the 10 years we would have more than enough in there and still 10 years out from being able to access it.I do plan on doing 401k loans for deals if the numbers check out, and I've considered rolling over some of our 401ks into roth IRAs to access our contributions but we'd have to pay taxes out of pocket (a big hit to cash flow) and we couldn't touch it for 5 years.
