Happened to me not too long ago, I found a 12 month 0% financing for 12 month credit card.

So i hired a property management company to take over while I moved away. the tenant moved in in May. my first repair bill was for $447.02 the next bill was for $734.32 that was for home depot to pay for the first repair bill. found out that the 442.02 was for labor only.

I am from England, so my questions might be culturally related.Question 1: “Ghetto areas” in LA

I’ve found a few promising properties in LA zip codes that, according to Best Places & City Data, have high levels of violent crime.In the UK, we’d call such areas ghettos and they are not worth investing in, as the tenants lack income, the monthly rental prices are low, and the property management companies provide a poor service.

I'm not sure how I found Biggerpockets but it has been an excellent resource!

The second part is that I've been looking into this a bit and have found online classes I can take that are based in Massachusetts.

This sounds like the price is too high or they have found a better deals after closer look.It really depends on many factors, like what is the exact location, what is the shape of the lot, how is subdivided,  how is it accessed, how far are the closes utilities, are those private / public, is there any public access, are the access sufficient or do you have to build a new roads etc. 

You've found a great place to start with this website.

I have found a lot of good resources already in my short time here!

I chose to releverage the desireable ones and 1031 the less desirable.I found the replacement properties mostly off market, through mail. 

I found my mentor during my schooling and now that person is my business partner.
