In one month I got 10 tenants at 100/month, also I have turned a 40 foot container into 2 workshops at 250/ month each .

All,I currently live on 5 acres of land with my home towards the front of the property and a 960 square foot workshop/garage about 160 feet behind my house.

You'll find going for your first sale will slow down your training on other things, a reasonably stable yearly income level normally takes 18-24 months IMHO, becoming really good could take the rest of your life....

Just make sure you have a good foot soldier or two there.

Is this a normal practice/fee?

I invest in tax deed properties in Ohio, which has a slightly unusual system in that if you 'win' a property at auction, you only have to pay a deposit on the day (usually around 10%), and the full amount is not due until the sale is confirmed by the court (ohio is a judicial state), which is usually a few weeks later.This is sort of like having a property 'under contract', when you would normally go off and try to get funding for the rehab / a buyer etc.

These are normally called Ownership and Encumbrance (O&E) reports, but I can't remember if those are legal in MA...it's been a while since I've been in the business.

I know that I couldn't ever afford to live there though, as I live in a 2006 Built, 2500 Square foot home in the suburbs of Indy I bought for 90K, But I would like to invest in SF with those returns.. 

You have come to the right place to start out on the right foot.

I normally call references and run background checks on the first applicants to give me applications and fees, and move on to the next if the first one doesn't qualify.
