Then let me be UNhelpful and give you the actual rules:  https://www.biggerpockets.com/forums/51/topics/1167632-expla...Pretty much everything you listed needs a 1099, but for the labor portion, not the materials such as paint.

Here’s what I did/would do if starting over with flipping:You need these basic skills, Finding money, Finding a house, Calculating an ARV, Negotiating with the seller if you are sourcing your own deals, Estimating rehab costs, Managing the closing process, Building a scope of work, Finding and hiring contractors, Inspecting work and paying contractors, Selling the house (Staging, listing, negotiating with buyers, closing process).1. 

Shop your hazard insurance, raise your FICO, put a larger down payment to get the PITI down.

You might be tempted to think you can keep track of everything in your head or just use the transaction listing from your bank account to see everything that’s happening financially in your business.

No board, no MLS, no license, typically no buyer agency, no title insurance, no mortgages, buyers go unrepresented directly to the listing agent. 

We worked with a local agent that we really enjoy and this house was listed on the MLS.

I always suggest doing a CMA of comparable listings which we can help with in Quintana Roo. 

Hamlet please don't be offended but the points you listed above are fallacies, and I hope you will realize that with some experience and education.

Purchase price: $67,000 Sale price: $77,000 Found this lot on Zillow listed by the owner, texted him and negotiated a 10k reduction from asking price.

On the off market side I just need to build better lists and get the right phone numbers.
