Purchase the property from your example and now monthly debt increases to 2.9k and monthly income increases to 5.9k, new DTI=49%I believe to do this strategy numerous times you would a.) need to get smoking deals or b.)have a high monthly income 

It contains the most important forms: application form, lease, ruels and regulations, lead disclosure, smoke detector and CO2 notice,  pet agreement, non standard rules (lawn and snow etc), 5 day notice and folders. 

I would verify the rent rate and your exclusions first  (Smoking, pets, etc).

It seems that there is a very limited number of well-known places for online marketing (MLS etc, Craigslist, Facebook, Instagram) so, aside from advertising on the Dark Web somewhere :-) , one's personal connections is the main way to bring additional buyer leads.

The tenant is incredibly difficult to deal with as she smokes in the home, doesn’t pick up after the dogs, doesn’t maintain the property, and rarely pay rent on time.

Would I be able to paint the ceiling with dewaxed shellac to cover the smoke stain ,(and smell) without cleaning?

Even if they swear they'll never smoke inside, they will, and will drive your other tenants nuts and it's expensive to get the odor out.Get your tenants to pay online so you aren't chasing the rent check.Be direct with tenants. 

Once in the daytime, and once after dark (9:30 pm-ish).You could probably accomplish both drives (on every street in the zip code) in a couple of hours each, and still have time to hit the zoo and see some incredible animals, and Cedar Point is not too far way either (it's the Roller Coaster capital of the world).

Very unlikely, @Macklin Baldwin, unless you get a smoking deal.
