We have been studying Buffalo's market and it looks really promising. 

The most important thing is to know the details of your local program like the back of your hand, then look for loopholes.Just to give you and the other BP'ers a deeper handle on why some TDR programs work and some don't, I just uploaded an excellent study on the topic to my FilePlace at http://www.biggerpockets.com/files/user/ChrisNewma...

Any such study is tainted by the fact that Zillow lost an enormous amount of money on their own home buying initiative.

Study the market.

I am new to biggerpockets.com so forgive me if this has been discussed already but, does the brrrr method work when working multifamily and if so can someone send me a case study or what the difference is 

Study all strategies, markets, etc, and find what fits your strategies.

It can work, but you have to really study the numbers to see what makes sense. 

However, the problem is that I currently live in Northern Ireland and will go to university either at the University of Edinburg, in Scotland the London School of Economics to study economics and politics.

I’ve taken time to study markets in each state and identified a few promising opportunities.

If you had 20 years of experience, great connections in the US, and knew your market in and out then I would say you could probably leverage at a higher rate and could probably manage that risk because you have substantially decreased all of the other risks.You should really study what happened in the US during the 80's when overleverage on real estate put a lot of people in a bad spot.
