But in a rising interest rate environment, the benefits are obvious.

I understand this is a popular question but the forum is too large to go thru all of the posts

I could be wrong though.. just like contract for deeds are popular in some states and in Texas looks like no Bueno :)

They are low maintenance.I personally have zero interest in installing a camera of my own at the property (many reasons, including: one more thing to maintain, no internet in my name at property, cost, any other issues like this that arise because of it, etc.), but I'm having trouble forming an opinion about this, so I'd love some feedback - pros, cons, etc. 

Wholesaling, wholesaling, wholesaling is the most popular answer I’ve heard/seen as the best way to get rolling in this industry, especially for those with low funds.

Take care of your properties, attend to issues as they arise, perform semi annual inspections to make sure your property is running to par and provide a clean and safe environment for your tenant.

From there give them your payment instructions as well as your preferred method of contact when issues arise.

Equity lines, Helocs and arm products were very popular before the recession, not so much now.

Aren't maintenance costs just that, regardless of when they happen to arise? 

I would consider doing the minimum down using your HELOC as they are interest only typically and we are in a rising interest rate environment.
