locally I've seen a number of posts to social media from renters who are having a hard time getting in touch with their landlords and/or getting them to deal with damage that's made the house unsafe or uninhabitable because of a downed tree or other obstruction.  

We priced it at $1,200 which was in line with pricing on Craig's List, Zillows, Trulia, Rent.com, Hot Pads and local social media rental sites.

For the most part that is true however, after reading a book called "The Deallionaire" by investor John Lee from Missouri (He was a guest on the Jennifer Hammond show), He talks about selling properties that he has bought  for less than $1000 using both conventional and unconventional means such as advertising a property via craigslist, social media marketing or selling through realtors and word of mouth.I'm mainly looking to venture into North Carolina, South Carolina, Georgia, Texas and possible New Jersey for this.I have heard both John Lee and Ankit Duggal (A guest on Bigger Pockets show) mention buying into tax deed/tax liens AFTER the main auctions by simply requesting a list of properties that were still unsold. 

I was told, by a website developer, that it's not a good idea to put rental applications on your website, because of the liability of storing personal information, specifically social security numbers.

My only problem is I don't know anyone that is willing to do it. i marketed it on my social media and nobody seemed to want to do it.

I think those numbers are for the average incomes. usdebtclock.org pulls income information from the Social Security Administration which uses median incomes. https://www.ssa.gov/oact/cola/central.html

Does anyone know how to social media as an effective replacement for in person networking?

If you and your wife ran a sole member LLC which earned income that needed to be reported on Schedule C, then you can each file your own Schedule C for the LLC in order to properly split your SE tax between your Social Security accounts.

Assuming this strategy works for your finances.Some other factors to consider are how well they take care of the unit, whether they are on fixed income/ability to pay more), your views on affordable housing/social justice, current market conditions (right now seems good for attracting a new tenant), and whether the property still cash flows or works at a below market rent.  

Deals are harder and harder to come by but we utilize direct mail, skip tracing, referrals, social media, door knocking, the MLS and others to get deals.
