After installing the exterior wood (make sure the piece matches the existing pattern), install exterior caulk to make the gap water tight.

Posting for the first time on Bigger Pockets.Do not know if this is even the right forum...Background is not in real estate but in Data Analytics/Data Science - analyzing and determining patterns in large data sets (millions of rows of complex data).Interested in initially researching before actually investing.Really would like to determine the type of data that I should review to quickly determine if the local market has potential or not.

Or was it more of a recurring pattern... such as first week of the following months etc. etc.

@Fred Avery just make up a number based on the weather pattern.

This is true even under the TCJA, with the reduced C Corp tax rate and assuming the business is a "Specified Service Trade or Business" the owner is phased out of the 20% QBID (i.e. the worst case scenario for an S Corp under the TCJA).I find C Corps only make sense in very limited fact and goal patterns (e.g. foreign ownership, when a company is anticipating going public, and/or when owners want heavy fringe benefits).Don't forget you get taxed when you extract capital from a C Corp -- either via salary or dividends. 

I’d like to buy single family homes and do a rent and hold pattern to generate this extra income.  

I just happen to know their historic selling pattern based on actual data. 

You should also be looking at demographics, traffic patterns, and of course getting bids on the cost of rehab.
