I don't have a CPA and have been doing my own taxes, but after purchasing the last two properties I need an experienced CPA to help me get all the tax benefits that I can.

Don't forget property taxes can be nearly 2X more for an investment property. 

Otherwise, look at the investment from a perspective of the basic annual cashflow and then determine if you would be able to gain any significant benefit from the depreciation or other tax benefits of the investment (speak to your CPA on that matter).  

There are also tax considerations, such as depreciation and IRS Section 121 Exclusion.

I'd rather just take my lumps and pay the tax as I don't think tax rates are going down anytime soon so my capital gains tax on my profits are about as good as I'm ever going to be expected to pay. 

There is also appreciation (gentrification area for this one), debt pay-down, and tax benefits of owning it outside of the cash-flow. 

Most often I'd hear people say:1) High taxes - but this can easily be reduced/eliminated by proper accounting and management.

Third, they pushed him to buy device from a tax person asking for $600!!!!

If you read and understand the instructions for a 1040 tax form schedule e, you basically now understand how to make money renting out property.  

Who's going to claim the 1098 interest from the mortgage on their income taxes?
