Brief surveys and polls are everywhere on the Web.

These days most jurisdictions seem to have one sort or another of pamphlet, web site, or etc that clearly explains their adu permitting process.

With that said, if you continue to rent you will have numerous tenants.   

Here's a recent one that suggests PenFed: https://www.biggerpockets.com/forums/52/topics/897411-need-a-line-of-credit-on-a-non-owner-occupied-rentalAnd another one from a few days ago that suggests TD Bank (and also mentions PenFed and US Bank): https://www.biggerpockets.com/forums/52/topics/898504-td-bank-heloc-investment-propertyAnd there's numerous lenders listed in this post from a couple months ago:https://www.biggerpockets.com/forums/49/topics/879963-helocs-on-investment-propertiesYou'll just need to call around.

I’ve bought numerous properties that I’ve never been inside, but I buy them at about 10% of appraisal from what I can see of the property.

I've read numerous books and rarely have come across any information relating to section 8 housing (and even those snippets haven't been terribly helpful or accurate).

The reasons for financial problems are numerous and varied.

Unfortunately, we have had to apply this across the board even if tenants have been late numerous times in the past. 

The only concern I have now is it mentions cat 3 water which has all type of definitions on the web.
