There aren't any secret strategies in this business and all the information you need can all be found with a google search.I quit my job with Amazon almost a year ago and hopped in this full time and have been pretty successful - I never took a course, just used my free time wisely before I quit my job to educate, educate, educate! 

Go on the IRS website and obtain an EIN as a sole proprietor - free and instant.

A knowledgeable CPA is a must if you plan to continue in this business.With that being said, flipping is considered active income by the IRS, so it is taxed as ordinary income.

You will get an IRS form at the end of the year showing all interest paid, and you can write that off. 

Also, you want to make sure that the interest being charged is at least above the minimum requirements of the IRS. otherwise, the IRS can charge imputed interest.

Taxes are done waiting for the irs to start accepting on the 28th.

I just did one with a 3.25% IR and 6 years in. 

for Tax reasons, you should have started marketing it for rent when you bought the property. but start marketing it NOW show photos and videos about the great work thats being done and show the draft of the finished product. start generating interest now and prove to the IRS that your intention for this property was always to hold long term so you can properly write off and expunge certain tax obligations.

So I just switched from my old, used-to-be-a-CPA, to a new IRS Enrolled Tax Agent.

Then have those smaller LLCs under a larger LLC in Nevada IR Wisconsin.
