Thank you, Jeff. Yesterday, we posted a new earnings package to our website, which provides more details on our financial position and operating results. Each quarter, we will try to add additional pertinent detail that will allow you to better understand our operating strategy and business platform. In that regard, I encourage everyone to review this package and let us know if you have any questions or suggestions. In addition, we intend to file our second quarter 10-Q later today.
Now on to our 2018 second quarter results. Total revenue was $13.2 million for the second quarter of 2018 compared to $7.4 million in the second quarter of 2017. In the first half of 2018, we generated total revenues of $24.8 million compared to $12.1 million in the first half of 2017. Additionally and on a sequential basis, total revenue increased almost 14% from $11.6 million in the from -- in the first quarter of 2018. Revenue growth continued to be positively impacted by our acquisition volumes and the terms of our underlying leases.
Total expenses for the second quarter of 2018 increased to $11.9 million from $8 million in the second quarter of 2017. For the first half of 2018, total expenses increased to $21.5 million compared to $14 million in the first half of 2017. Depreciation and amortization expenses as well as interest expense remain large components of our total expenses as we continued to be an active acquirer.
G&A expenses as a percent of our revenues continued to decline as a result of our cost-reduction efforts and increased portfolio size. For the 3 months ended June 30, 2018, G&A as a percent of our total revenues was 13% compared to 25% in the comparative period. For the first half of 2018, G&A as a percent of total revenue was 11% compared to 28% in the comparative period. These results were primarily impacted by an increase in noncash LTIP expense, offset by a decrease in Sarbanes-Oxley implementation costs and other professional fees.
Please note that sequentially, our noncash LTIP expenses increased from $182,000 in Q1 to just under $1.1 million in Q2. This increase was driven by the increase in our share price at June 30 compared to March 31. Looking ahead, based on our June 30 share price, our stock compensation cost in the second half of 2018 will be slightly above $700,000 in each quarter.
As we continue to look for ways to actively reduce cash G&A expenses, we anticipate that in the second half of the year, these G&A costs will range between $1.5 million to $1.7 million or $750,000 to $850,000 per quarter, representing annual run rate ranging from between $3 million and $3.4 million.
Our 2 largest expense items in the second quarter were depreciation and interest, both of which are positively correlated with our portfolio growth. Depreciation expense was $3.4 million in the second quarter of 2018 versus $1.9 million in the prior year quarter. For the first 6 months of 2018, depreciation totaled $6.4 million compared to $3.2 million in the comparative period.
Interest expense was $3.9 million in the second quarter compared to $2 million in the second quarter of 2017. For the first 6 months of 2018, interest expense totaled $6.6 million compared to $3.1 million in the same period last year. These increases in interest expense during the second quarter and first half of the year were primarily due to the higher average borrowings during the periods.
Reflecting the impact of increased rental revenue, we had a net loss attributable to common shareholders in the second quarter of $64,000 or breakeven on a per-share basis, which was up from a net loss of approximately $623,000 or $0.04 per share for the comparable period in 2017. For the first half of 2018, net income attributable to common shareholders increased to approximately $346,000 or $0.02 per share compared to a net loss of approximately $1.9 million or $0.11 per share in the comparative period.
Due to higher rental revenue throughout our portfolio, second quarter 2018 FFO increased to $0.19 per share, and AFFO improved to $0.20 per share versus $0.10 and $0.14, respectively, in the second quarter of 2017. On a sequential basis, FFO and AFFO increased from $0.18 and $0.16 per share, respectively.
For the first half of 2018, FFO increased to $0.37 per share compared to $0.12 per share in the comparative period. AFFO in the first half of 2018 increased to $0.36 per share compared to $0.23 per share in the same period last year. For the first half of the year, FFO was greater than AFFO primarily due to the impact of straight-line deferred rental revenue adjustments, which impacted AFFO but not FFO.
Moving on to the balance sheet. As of June 30, 2018, our portfolio of real estate assets was carried in our balance sheet at a gross value of $602 million.
Looking at the liability side of our balance sheet. We have total debt of approximately $327 million, which included $288 million that was drawn on our credit facility and $39 million of fixed rate notes payable. At June 30, 2018, the weighted average term of the company's debt was 2.05 years with a weighted average interest rate of 4.38%.
Subsequent to quarter -- the end of the quarter, we amended our credit facility, increased its capacity to $350 million, which includes a $250 million revolving credit facility and a new $100 million 5-year term loan. We also extended the term of the revolver to August 22, with a 1-year extension option. The facility also includes an accordion feature to increase the aggregate capacity up to $500 million. In addition, we were able to hedge our interest rate risk on the term loan by entering into a swap agreement that essentially fixes the LIBOR component on the term loan to 2.88%.
Lastly, in June, our Board of Directors declared a second quarter cash dividend of $0.20 per share, representing an annualized rate of $0.80 per share and a dividend yield of 9.4% as of the closing price on August 7, 2018.
With that, I'll turn things over to Alfonzo to discuss the company's acquisition activity.
