Onlinejobs.ph is the best source that I've found for people you'll keep consistently employed. 

Hello All!I’m looking to get started in long-distance real estate investing and have been doing lots of research on several markets to try and select the ideal market based on my strategy. A problem that I’m having is...

Does anyone have any funding sources that would be willing to work with a newer investor and use the property for collateral to secure their investment for the the rehab funding?

So I dont have roots here.

There is no specific science to it, and I would use more than a single source for rent estimates.  

Sorry, I can't recommend a particular source.

If anyone has any tips, alternative methods, or source material to throw my way it be greatly appreciated.
