I have done exactly that in the past year.The IRS is specific in terms of business deductions: you have to show that you are in business to make money - so that the IRS can tax you on the profits.

They took a 5 acre parcel I had purchased to build new transmission lines and re-conductor old lines in order to provide power from a new utility scale solar generating plant (solar farm) they had constructed.My attorney hired the appraiser with only 2-3 weeks prior to the date our expert witness and discovery production had to be turned in to the courts.The appraiser found very low comps in the area.

For example, if default loan amount is 100K, how much will the legal fee also include any cost generate by this?

The price point at which you would be able to afford these properties means that average rent would be roughly 5-600 per unit, which attracts low quality tenants, and means that neglected repairs and capex items can quickly eat into any profits that you may think you are getting. 

Your network is your most powerful lead generator.

In my marketing plan I do intend to use my website for lead generation/SEO but I don't want to wait until I get the website going until I start my mail campaign.

I want to make profit from renting them out.

[Regarding your tax minimization questions, I'll just say: I only recommend Investments that would have you making a PROFIT!

The short answer is no,don't do it.You don't seem to be in the right mindset to become a member of my profession which is exactly what it is,a profession and not a hobby to pick up or put away at will.My profession requires lots of time devoted to learning both in and out of the classroom for at least 6 months to earn a license and the follow up sales training at the brokerage.It is not cheap either to get started with all the fees involved.From what you are describing about your personal life,family demands,and interests desired to pursue,I would concentrate on learning about investing in your spare time.Learn how to evaluate property for potential profits after repairs are done.Join an investment club and surround yourself with successful people who have already been through the process.Learn about hard money,gap funding,and what it takes to get the money you need when you need it.
