Hello My nama is Jules bByabagabo, live in the Maine state in brunswick areai'm new to real state investor and looking to connect with any local investor. thank you

The two riskiest elements of a standard Flip or BRRRR are the mortgage and the contracting. 

This is all alongside listening to the bigger pockets real estate rookie podcast and the main podcast.

Here's a https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-report to the IRS website noting specific items that are included in the cost segregation study report. hmm, that website is a 404 error.  

This is why many experienced investors in cities with old housing stock (I am in Philadelphia) intentionally buy property that requires full gut rehab - to change out all of the systems and structural elements and remove most of the need for ongoing expensive maintenance. 

For BRRRR investors, a crucial element often overlooked after the rehab, especially when considering a cash-out refi, is leveraging cost segregation.

Gold and Silver are monetary metals and canaries in the proverbial financial markets mine...I think we first posted here about AG at $1200 and AU the $20's..anyhow..clearly elements do not change but the denomination does and if priced in money (not currency) prime real estate in many markets could be undervalued - particularly when investors consider the exceedingly exotic methods of leverage and abundant tax incentives available. 

Like John asked above, are you seeing amenities or design elements in other successful Airbnbs nearby that you could copy? 

It also touches on RMD starting age elements and additional tax rules affecting early distributions.

Generally, look for baseline deals with a modest return, standard cookie-cutter properties, avoid any element of speculation and buy quality homes in good areas (as opposed to a full rehab in the hood).
