I am not personally a wholesaler, but my friend Bill Allen, hosts a phenomenal event every year focused on building systems for flipping and wholesaling.

All systems are gone. 

Here are a few requirements to be eligible.The build date of the property is between August 5, 2005 and December 31, 2021.The property is between one and three stories.The builders incorporated features that are energy-efficient such as high R value roofing, insulation, HVAC systems, windows and doors.What are some examples of specific requirements for this tax credit?

@Graham Allen Find a niche that you like (ex. single family residence, near a military base, or a STR in a vacation place or near a large hospital system?) 

Their system has treated me well. 

FHA financing is intended to put people in their own home not be a low down payment system for investors.

It seems like the system is set in a way where landlords can't really improve the condition of their house without knowingly loosing equity or cash flow. 

Ideally, once you have all the systems in place you take the best deals to flip and then wholesale the ones that don't have as much meat on the bone or are higher risk.Either way, both wholesaling and flipping are challenging and I would consider them a very active form of investing. 

And if it was built around 1900 I would want to know what kind of condition the plumbing system is in and the electrical is probably way out of code.
