The lack of sex appeal and the relative undiscovered/unloved nature of MHP's were major draw for me.  

If you are relatively new to Real Estate investing, check out my blog if you have time.

I just saw a post yesterday on this & the takeaway was it may not be possible if both people on loan are not residing in property or directly related, I believe.

What I'm hearing is that the Real Estate Professional designation is not directly related to what deductions a real estate investor could or could not take.It seems I do meet the requirements.

You can qualify for the good loans, manage everything and gain great experience.I got started at your age buying a duplex and living in 1 side, renting the other. 

I wouldn't consider age so much so long as the neighborhood it is in can support your sale price.The best way I can say is to always follow your market and visit some homes personally and eventually you will just know what a certain property is worth and won't need to necessarily find comps

He ask us why we didn't go thru his bank, and it would be simpler because of the business relations.

While they are relatively new, it was free for me to sign-up and try out, so I decided to give them a try.It has been great thus far, considering it is the first time that i'm using a software to help me manage.
