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.

I've caught the bug--my goal is to have 10 properties and/or $4,000 in cash flow by age 30. 

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.

Unfortunately if you just look at the data in their web interface, the CC processing or related fee is not reflected. 

Bought it for $180k 5 years ago as a buy and hold.Developers are putting $400-600k homes on tear-down properties all around it.I looked at tearing down and putting a 4-plex on the lot...not allowed per code.I looked at tearing it down and doing a duplex...after all costs and penalty of interrupted cash flow...bad move.I looked at tearing down and putting two single family homes...bad cash-flow move.It just seems that with a lot so large relative to the size of the home is in such a hot/in-demand area, i should be able to get more cash flow. 

How will the commission and all expenses related to the selling affect the gain?
