I have view places to purchase and found bongs in my walkthrough (most people might not look under the kitchen sink, but when buying a house it is a common place to look), I have had tenants complain of noise from other tenants and mention other tenants smoking pot.

Also, for any of you with experience with this type of thing:Should I expect problems, such as roommate squabbles over cleaning, noise, etc.

Additionally, in this first year, you will need to save $10,000 outside of real estate, you need to continue to grind and hustle.

You need to grind...step 1 is refinancing it but keep the same $900 payment (I would double up on the amount to pay down each month), don't refi to a $650 payment and think, oh nice, I only have to pay $650. 

It's about hard work and due diligence and putting in the grind and hustle.

The reality is that it becomes white noise.

Same noise issues, but much more privacy.

Now closing in on 20, I couldn't imagine doing this without that substantial monetary incentive each month.For me It would just be too much of a grind to be highly leveraged and deal with day to day issues!

Some accounts just fail to sync and grind forever.

Why not just grind your way up by purchasing 1-4 unit deals, and once you have a proven track record of success, moving on to progressively bigger and bigger deals?
