When I'm in doubt of a potential cost I get the written bid before I even make an offer or while I'm still in my inspection period.

For your last question about the inspection period, that depends on what the agreement you plan on using says about the inspection period.

I've read David Greene's BRRR book and as the article mentioned, it says nothing about DSCR in it.As for Conventional loans, from everything I've read on BP they're now a 12 month seasoning period.

This wholesaler was clear that their contract doesn't allow for a due diligence period.

I had a client invest in Albany, and ended up liking it so much they moved into one of the units for a period of time.

This requires us to do periodic "maintenance inspections" and we keep an eye out for rental agreement violations at the same time.Hope this helps!

I can see/understand the zero/sum game.And copy on the focus for building during this time period.

Period.

But is performing.If you keep doing this periodically you'll end up with a fleet of free and clear properties free of risk and accomplishing your retirement goals. 

Plus, the new systems flag activity during time periods so you don't have to look through all 24 hours to find movement.
