Now if its a smokin deal and the 3 to 5% is easily absorbed then its worth it but you still need cash down  .. or you need a friends and family's to help you out.leveraging up 100%  to buy rentals you want to be careful there if you don't have a bunch of cash reserves since your tying up your heloc for the purchase  leverage to the eyeballs can be great if everything plays out perfect  if not it can be highly stressful.  

I was able to absorb my current mortgage with an additional mortgage and meet DTI requirements.  

I want to absorb as much information as I can and land some type of property deal within the next year or so (by my 21st birthday if I can in May).

Just hit them with a big increase and see if they can absorb it.

There's a lot of really good information out there that can be absorbed while you raise your initial capital (if not already done).

This takes a LOT of my time.If I went to get a judgement against this tenant for the balance of the lease (if I could even find them to serve court papers), the judge would tell me to go pound sand, absorb it as a business expense, go re-rent the apartment, move on with my life and quit bothering him with this "nonsense."

However if you are able to absorb some risk because you could recover on the backside then your options open up - like I said, define the end goal first.All of that being said ... 

I have been absorbing as many of the BP podcasts as I can and reading all the books I can on this.

I would have a lawyer review and see their material/labor increases to ensure that is all your absorbing.

If you're doing enough business to absorb the fees/mls dues and you make the commissions when you buy/sell, then it makes sense.
