New to RE investing , can I claim taxes fees on RE mentor/coaching, including Real-Estate software system package as RE start up Business cost? 

It should apply, as a veteran myself, I have a soft spot for other vets using their VA loan to get started in real estate (it is how I got started, and it is easily the greatest loan product available). 

I was recently advised to look into wholesaling real estate as either a way to supplement income or create an entirely new career for myself.

Do you live locally?

Russell, the property owners terms of note secured by the real property, unless in foreclosure, have little to do with the tenants obligation. 

You can also talk to hosts in local Facebook groups in areas you are interested in.2.

If I want $400k a month I am in commercial real estate and luxury office in downtown area like K st dc etc.

I'm  working on "ABCs of Real Estate Investing" by Ken McElroy and "Confessions of a Real Estate Entrepreneur" by James Randel, all of which have I've taken some great ideas from.

As far as I'm aware, SBA loan programs cannot be used for real estate companies.
