Can anyone recommend courses/ways for me to learn so that I can become a competent investor? 

Especially if the building is less than a 15 minute walk to the train.

I of course did not get this sent before I submitted an offer.

Once the foreclosure process has started, you can only get the train back on the tracks if you can pay off their loan and liens, which someone probably would have done earlier on a short sale if the upset value wasn't too high.

Of course, you have to be certain that the town has issued a license for the number of used cars for sale. 

Then of course would need to go in person and evaluate.

It’s about changing the culture of your tenants and training them how to work within the system you have created.

If they're selling course after course, no thanks.

The first question is of course, can you get a loan with less than 20% down - but I'll assume you can given that you're exploring both options.I recently read Real Estate by the Numbers by J Scott & Dave Meyer (shameless plug it's available through the BP bookstore here) and in chapter 36 they discuss exactly this - that in some cases using more leverage can actually boost your returns and you should run the numbers both ways to see what makes sense for you.

Any information would be greatly appreciated as Im not sure exactly what would be the best course of action.
