To me, house hacking is the gateway way drug of the real estate world.

If drugs are an issue he can try to get the guy arrested off site especially if he knows  where he is selling stolen property or if he has drugs on him.

I'd call it a D not an F, maybe some F blocks mixed in depending on recent gang/drug sales situation.

True DSCR loans won't cap you or limit you based on your Debt-to-Income because they recognize that the debt that the property incurs (P&I, taxes, insurance, etc.) can be covered by monthly rent and if you can find properties that 'pay for themselves' then they will lend you the money to find more and more.Some DSCR programs will even alleviate on your personal credit and only require soft-pulls.

Your standard ghetto Cleveland duplex complete with all of the normal ghetto duplex type stuff....Drugs, crime, blight, evictions etc...What was different about this duplex was the out of state owner is/was a total lunatic.

Just be sure to assume your project will be broken into and tools stolen and have to deal with squatters and drugs.

Compare this to some as expensive as $1,000 per month and even those expensive options having large copays, limited networks, and they'll even refuse to cover some non-generic prescription drugs!

Verbally abusive, demanding things from me that aren't my responsibility (demanding that I fix his suite door because he forgot his keys and kicked in the door rather than calling me, demanding that I drop everything to personally come and adjust the thermostat because he's cold, when the thermostat is always set the same and never changes, etc), being nuisance to the upstairs tenant, falsely claiming things I've done, removing wired in smoke detectors, doing illegal drugs on the property. 

That's where this idea came to mind to alleviate some costs when it came to finally purchasing something.  

No investment properties, this is my first purchase also why I'm using a GC to hopefully alleviate some experience concerns.
