Does anyone here have any solid property management companies you work with or recommendations on how to vet them when interviewing them? 

My brokerage doesn't do property management, so we recommend Rachel Bruno with Re/Max Unlimited to our clients. 

Any realtors, developers or sellers you recommend working with, in Puerto Vallarta, Mike?

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

.- If you purchase a property that you can visit and want to maximize cash flow for the next property, I recommend looking in places like Bremerton and Burien.

It's not all rainbows & unicorns, but the city has turned the corner on recovery and those that get in now, in the right areas, should ride a solid recovery wave to wealth.Now that we've covered that, read our standard copy & paste advice about rental investing below:)Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.So, when investing in areas they don’t really know, investors should research the different property Class submarkets.

Do I keep a record of it somehow, and, if so, what is a recommend way to keep this record? 

Recommendations welcome-thanks in advance! 

If you are looking to take cash out of an investment property, I recommend looking into a DSCR loan.

Once you know this, I may be able to make some better recommendations.
