Personally a cash-out refi could help me get more quickly into all-cash BRRRs or a REI venture in Spain, however I don't know to what extent this is at the expense of rental cash flows, and what is the wiser decision long term.I've combed through posts online and looked for Excel templates to run some calcs and get a sense, but nothing really filled the void... 

You could comb through each lease and make sure no one has broken any of the terms.

I get a better sense of the area's market when I look through sold properties with a fine tooth comb as the saying goes. 

BUt I really should comb through the replies and add more wrong number tags in my contacts list. 

@Brandon Combs yeah absolutely.

Most leases have occupancy rules so the truck driver is who you signed the lease with, the other occupants don't have legal rights to live in the property, you should be able to get them out based on that alone.I would go through the lease with a fine tooth comb to look for violations, and also hire an attorney as was previously mentioned.

On the other hand, I have scoured his web site with a fine tooth comb and I cannot find an email address, a phone number or a physical address anywhere.

Thankfully my HOA is very investor/rental friendly (which I was considering when buying) but that is a really good thought I need to comb through those details as I hadn't thought about how much parking is allowed and I'm sure there are some other considerations I am missing.

Look over bids with a fine tooth comb, no bid is the same.

If you are good at underwriting, partner with someone who can find deals or bring in money, or partner with multiple people that by combing forces you all can handle your own area of responsibility for the overall success of the team.
