Had an issue with trying to self-permit a build a few years back that was an HPR but had an "A" and "B" designation.

Unrealistic construction budgets are an issue new investors often face.

This issue also naturally drives up deductibles.  

Of course when doing the 1031 exchange your basis will carry forward into your replacement property.Where you have a potential issue is establishing your intent to hold those properties but immediately selling one or more them as soon as you have them ready. 

It was high rent, low entry point area but within 6 months I dealt with an eviction and electrical issues.

Turning the management of the rental over to a property manager can relive a lot of these issues.

One of the issues I have noticed is that some people think of a flip house as being the cheapest possible rehab. 

Beyond immediate safety concerns, the long-term financial implications, including taxes, are a pressing issue for those impacted by the disaster.

I had constant issues with the local government and the taxes were absurd.

Take care of your properties and follow up with issues.
