use a pro the first year. as a purchaser of a business form 8594 probably needs to be filed. this is an asset allocation statement required of both the buyer and seller. Turbotax does not support this form. the IRS uses this form to check to see that both buyer and seller allocated the price the same way. second, what was the extra $20K for? It may be amortizable. third, the equipment may not be 5 year property 7 years is possible. forth, $32K the first year is not allowed. you can use straight line {Straight line election. Instead of using either the 200% or 150% declining balance methods over the GDS recovery period, you can elect to use the straight line method over the GDS recovery period} but there is a convention that applies to the first year which does not allow a full year's depreciation (you get it over 6 or 8 years). also to use straight line you must include an election to elect out of bonus/special depreciation
