I have a fair understanding of home mechanics (plumbing, electrical, etc) but I  contract these tasks out almost always.Looking for connections for our next purchase (later this Fall) as well as fair contractor services (general needs in regards to routine / urgent repairs .

I will incorporate these into my routine to ensure success of my company.

If you can repair it to routinely work correctly then no you don't need to replace the door.

Reality is more painful, with vacancies, new roofs and routine maintenance all "eating away at the profits".

Keep records of the square footage of the office space and related expenses.Document Repairs and Improvements:Distinguish between routine repairs and capital improvements.

Long term major repair reserves should be at least 10% so there you have 50%.Now if your rent is actually $2000/month, insurance, routine maintenance etc will not be 10% but probably less.

If your wholesaler is taking title to the property (owning it), then it's pretty much a routine transaction.

Thank you hopefully I can keep with my daily routine and network enough to get my first flip in my belt bay mid year.

Let's pretend we're in NYC, where rents for studios routinely run $3000/month. 

. , we have income less PITI, less lawn care on the duplexes, less routine maintenance (5%), less turnover costs (7%), and misc items like education (1%).
