There are going to have a consistent feed of discounted properties.  

With that said, this is a long game and the ones who are successful are the ones who consistently put the effort in over time. 

However there are still solid, consistent investments. 

Absentee owner lists, in my opinion only, not fact, will likely have the lowest returns of success so quantity and consistency will be required to experience success.

Generally that criteria consists of cap rate not below 10.00% but occasionally I see properties 8-9 % and even 18-20%.

They've done so consistently in the US for the last 50 years.The average appreciation is over 6.3% annually at the moment for the last 50 year period.For as long as we've been tracking home values, there has never been a year that home values have on average gone negative.Economists have predicted 25 of the last 2 recessions!

Using a good brush and consistent brush strokes going in the same direction give it a better look.

If you are not willing to work at it consistently and persistently day after day, week after week, month after month, year after year, you will not make this into a successful business.

Mailing is cheap but effective only if you consistently doing it week after week, and then it is not cheap anymore.

Would they be a consistent source?
