30 year fixed 5/1 ARM

[Dan MacDuffie]

I am near closing on a house.  My plan is to buy house and rent it for 675.00 per month for the next 24-36 months and then sell the house (I will not own it for more than 5 years and maybe even less than 3).  The cost of the house is 45,000 and I am putting 20 percent plus paying for all closing cost.  My monthly mortgage will be around 450.00 --I just read about 5/1ARM type loans-- would this be a better option for me?  Please help-- Dan
