Did they inspect the house, list the repairs and estimates to fix? 

You might make 900/month on those 3 Gastonia properties that are the same price as one Harrisburg property that only cash flows 200/300 per month On the other hand, the Gastonia properties will have high turnover and the occasional drama from vacancy and/or needed repairs, that will decrease their valueLots to consider:  nothing is ever easy :)I can't imagine managing properties from across the Country. 

Even if you're planning on doing repairs, showings, leases, and all that jazz yourself, deployments are a thing and you'll want to have access to folks who can take care of things while you're away if they pop up. 

House needs - New furnace, new flooring or carpet in basement, and some other cosmetics minimum - $10k to $15k repair estimatePotential rent in my market would be $1,800I could also put a little more into the home and flip it.

I am using a credit repair company right now and my credit score went up from 580 to 620, which I was very happy about, but then I had to buy new tires and opened a new credit card with the available balance of 900 and had to use all of it.

I'm also a grad student so my financial situation is not actually the best and I'am currently enrolled in a credit repair program (hopefully that helps with potential loans if need be) so I was thinking that maybe NACA would be a great start to purchase a multi family to house-hack and product passive income.

Just as if the landlord is in default at closing (by let's saynot completing a repair in a timely manner) , the new owner is now in default as wellThe new owner can initiate the eviction process immediately.

VERY IMPORTANT: you must get familiar with repair estimates.

You could also focus on the great financial advantages of renting/down-sizing (travel more, no more yard to care for/repairs, buy an RV, visit family more)Host a senior-focused event at your facility (maybe show an uncut version of Woodstock haha) or live music, a Social Security expert speaker or Doctor to address health issues, a fund-raiser, art show, etc. and hand out flyers with a special "one month free" coupon attached Have exercise classes for seniorsWeekly bingo nightsPromote your events for free on community calendars, newspapers, seniors sections of papersPrint door hangers and get some kids to hang the door hangers at trailer parks, older communitiesEncourage your current tenants to invite friendsRent a 15-passenger bus ($50) and offer free transportation to key eventsSponsor events at senior centers in the areaCo-Sponsor service club (Rotary, Kiwanis, etc who have many senior members) eventsPut up banners and balloons when you have eventsI hope at least a few of those ideas might spark some interest.
