You can manage projects multiple ways, including hours + materials.

I don't think so, but they're a big event that gets hosted in multiple cities every year.

To add additional context,  I would personally be more willing to sign my name onto a $6M mortgage collateralized against a $10M asset in an "A" market that has historically low vacancy rates, no deferred maintenance and is located in a stable market with a rent roll that covers the debt services and operating expenses with reasonable cushion for reserves than sign my name on a $90,000 loan collateralized against a $100K property in a C/D unstable market with high vacancy rates and where capex will disproportionately impact operations.

Multiple issues emerged the entire renovation period. 

How did it impact your deal flow, especially when time was a factor?

I’m a Marine veteran who has spent most of my 15 year professional career post service in project management across multiple industries like aviation, hospitality, tech, and CNC machining.

They may seem attractive on a spreadsheet if you are chasing cash flow, but the fundamentals are not as strong and these properties are  disproportionately impacted by capex and operating costs.

With that being said, as long as your return is fairly straight forward, you should be okay but if you have multiple rentals and other things going on, always worth at least a chat with someone.

To me, this is a cost that won't "add value" to your BRRRR, so I would more strongly consider how much it might impact your ability to rent the unit/house.

@Matthew TurcotteI would look up Dave Hook, a really savvy investor who is in multiple asset classes.
