You want to delegate all the mundane tasks to others and focus on doing tasks that only you can do.While you are calculating the costs of all the raw materials, you also have to calculate your salary into the total cost of writing your own handwritten letters.

It is tough to pass the Self Sufficiency test right now. 

With that said, get materials ordered early - especially for kitchens and baths.

Surviving the first few years is tough, but if you can figure out how to do that, you can have a 3-5% down payment (call it 15-25k) turn into 300-500k of appreciation over a 10-12 year period.

I've even heard of GCs using auction type settings for returned items at Home Depot and Lowes for steep discounts.I've learned a lot about the GC game as I was up close to over 40 projects last two years and some went well and some did not and when they did not it was all Contractor related.If a GC isn't sourcing cheap materials at the same time milking the hell out of his 150-200 per day workers, then you can find yourself eating into your margins real fast. 

This being said, that would justify only a reasonable price increase caused by the cost of materials.

Yes, wholesaling is tough to break into and to do it correctly is to have a good foundation of knowledge on the subject. 

  - 10% on material  from Lowe’s/HomeDepot. - Capital partner that can assist with cash as needed. - potential equity in primary residence Asks/Needs to achieve goals. - In need of assistance formulating a concrete plan to achieve goals.- Assistance putting the knowledge and resources together to close next deal. - Looking to attend real estate meetups and expand network. - Locating and putting together the right  team that’s needed.-  Joining communities and connecting with others on a similar path. 

Like @Chris Seveney said we don't know a lot about you.The market is tough right now. 

Plus you’re optimizing for materials cost by reusing and buying some used stuff.
