Time with family, giving to a preferred charity, or just having nobody buying your time. 

They are both good; personal preference.  

@Aaron Zimmerman my old Chicago buy box (Albany Park, Rogers Park, Irving Park, Lincoln Square, Ravenswood Manor) has moved pretty far away from my preferred fundamentals.

It seems that having 5 units sends all the lenders into a frenzy as they prefer to loan on 4.

Engage an investor-focused realtor/broker in your preferred market (this is not a residential realtor) and start 'tire kicking' the market and properties that fit your criteria.

Quote from @Himateja Madala: @John Underwood with 6bed/6 bath I am targeting more multi family travelers who prefer staying together.

I'm looking to start off in areas with lower costs coming in, preferably under $100k single families but definitely under $200k. 

It seems like you would prefer the easiest and quickest way out.

Everyone has different opinions on this and it really comes down to personal preference.

An LLC also makes refinancing in the BRRRR method smoother, as many lenders prefer loans through an entity for multi-property investors.Starting with the right structure positions you for long-term success.
