They use tools to monitor listings and may even check other booking sites to track this.

You also need to be able to rely on project management skills to manage the project to stay on track.

To keep everything organized, I swear by Asana for task management; it keeps me on track.

The good news about BRRR is it will fast track your investing goals.  

@Patrick Franta yeah I'm tracking the taxes and HOA fees separately in the worksheet I provided.

I have kept track of all my expenses in an excel sheet/word document but feel like there may be a more organized and efficient method to tracking?

If entities are disregarded, you can keep up with more than 1 in a single QBO account using the location/business feature to keep track of them separately.

For instance, if the neighboring unit has a shut-in chain-smoker, or the house has railroad tracks behind it, it is definitely better to let a lead know and lose them than to not disclose, upset them and lose them (after they leave a nasty review).I'd agree with Jonathan that even late complaints need to be taken seriously, and barring some obvious malfeasance, I would just take the word of the resident and fix the issue.

I don't have a proven track record yet so I need a sponsor who does and can get great financing from the banks

Curious to hear the system you'd recommend for tracking material participation?
