Tenants today send me pictures and videos of issues without me asking them. 

While researching tiling over existing tile I found that it can be done and there are several videos on YouTube.

The audio will save in mp3 format.

There are also countless podcasts, YouTube videos, etc.Learn all you can, then look to fill any blanks you have left over.Understand you need to be prepared for the long haul. 

Learn how to pull comps (don't ever mention Zestimate again) and get up to speed on the basics of rehab costs.At first blush, if homes are selling for around $385,000-$439,000 in the area, that house is going to need more than $50,000 in work.You'll need to do a walkthrough with a contractor, who will likely charge you for the estimate.There are lots of youtube videos on figuring out how to estimate rehab costs.

I have also been hearing a decent amount about using video for advertisement. 

I watched Brandon's youtube video using the 4 square method and my CoC Return was 40.4% vs using the excel spreadsheet punching in the same numbers but coming back 10% lower.

Only in the case where you have worked with a specific contractor for a long tie and built a relationship/trust with him should you ever consider giving 50% upfront.Even with the great relationships I have now, I use a draw format.

Got that from a video by Jerry Norton, just found out about him on a topic of estimating for a flip.
