I however am always very leary on posting up great deals and spreads before the check clears from closing.

For example, did you establish your bring mainly website, social media presence, order business cards, virtual phone numbers etc or did you just jump out there? 

That was about $1500 spread over 4 years. 

Anyways for marketing, some good ways to go about it is to place ads on Craigslist, create landing pages to drive traffic to your website, market on social media, and put up signs in your target areas.

Our spaces have leased up quickly and easily via word-of-mouth/social media/networking to date, but they’ve also been smaller, less expensive, rehabbed spaces and very comparable to everything else on our few block long stretch of commercial storefronts.

Unconventional media?

Besides that, social media is the best marketing tool!

So based off this calculation I determined that my portfolio is strong enough to move on with my expansion plan into a new market.Business expenses as % of total expenses : 70%   1) Fixed Expenses:        a)Monthly Mortgages: 45% b)Property Taxes: 18.7%c)Utilities Expenses: 14.8% d)Licenses & Insurance:  5.4% 2) Variable expense - Water bills + repair expense : 16%  Personal Expense as % of total expenses: 30% My monthly living expensesa)Housing: 39.7% b)Child Care: 25.4%c)Living expense: 22.2% d) Food: 7.9 %e) Insurance: 4.8Income 1) Total Income - 100%  A) Rental Income: 42%  B) Wage income (W-2) : 26 %  C) House Flipping Revenue: 23%  D) Property Management Revenue: 5%  E) Stocks/Dividends: 4% Please let me know if you would like help walking through this process as it has been super helpful to understand my financial situation or send you the spread sheet I used.  

That being said I now have 17 units spread across duplexes, houses, and a quadplex. 

But the spread between current rent and market rate is my case was not as large as yours.
