Help newbie in analyzing property

[Ryan Taylor]

Hello I'm looking at triplex in Houston and I'm wondering if you could give a new person some help. The property is for sale at 107,000 per the realtor. Seller won't budge on price. 

Taxes are $2,400 water is $1440

Insurance $800  

Landscaping $175 every two months

Rents for $1600 total Realtor said: willing to offer 2nd mortgage for 25% full balloon in three years. Forgive me as math is not my strong point. Could someone please explain? 

Thanks in advance 

Ryan
