If your former kept your full $5,200 in initial security deposit it sounds like she's already making more money from you than she should. 

As a newbie agent, a bigger firm was nicer (just say you plan to be full time) because of all the great technology and training.

I think in this way atleast within 5 to 10 years I can pay off mortgage and will end up with full property value and rentals on monthly basis (even if I don't want to earn anything till 5 years I am fine with it)- Is this a good idea to invest in commercial property like this with big downpayment?

The property can be used as a hostel with 10 double beds, sleeping 20 persons in its full capacity.

The seller and tenant can sign their own lease after you're out of the deal.You also don't really need the LOI, that's just if you want to do a written negotiation without filling out a full contract.

I'm 26 years old with a full time job and want to start investing on the side until I grow my portfolio and profIts enough to be able to Invest full time.

Fight On!

I'm currently working a full-time and a part-time job so I'm not ready to try start my own marketing efforts.

So if you bought for $50K, put $25K in, and it appraised for $100K... you could get you're full $75K back out.

If you want to get your RE license and skip straight to a full time career, apartments may make more sense.
