I am new in BP, and I am looking to understand where I start with learning about REI.I currently live in New York which it's not a good place to start investing.i know the difference between STR,MTR,LTR....

Well, of course - that's obvious - but most people in most places in the US are going to spend too much on their purchase because that's what's available.

one of my clients that has a pretty big PM company.. had a unique way of doing this.He offered 50% of the first months rent or 500.00 minimum.. he would have 4 or 5 agents at the weekly meeting handout the list of vacants .. each of them would go place a sign in the yard and first come first served.. he found that potential tenants would call the first sign if no answer they called the next one until finally someone answered.. it worked pretty awesome for him. 

Where I am running into an issue is there is a delinquent account on my credit history.

But now things are working more smoothly and after finalizing the accounting for last year, I have a better idea as to what kind of profit to expect.  

@Steven HsuBigger Pockets is a great place to find a real estate tax accountant.A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

But when I'm Alberta, I have a place in Edmonton area.

Quote from @Amanda Dobbs: Is there a place to find Private Investors as in one person?

Both my wife and my background is in manufacturing, specifically operations, customer service, and project/account management. 

That place is a total joke.
