On Airbnb they argue Airbnb has already their ID.

I'd would even argue the best strategy... especially for Nomads.

And it’s not your average-paying jobs.I have seen our freeways get wider over the decades, yet traffic get worse (one can argue that it’s just same amount of people who are now commuting longer distances because they cannot afford to live close to their jobs.

I would argue that working with a remote CPA who has experience in real estate will likely be a better fit for you than a local CPA who is a Jack of all Trades.

You should do a little bit  better than 6% on a 30YF (unless maybe if that has PMI baked into it), but 85% LTV investment properties remain the highest interest rate conventional mortgages there are, holding constant things like credit etc.The investment property hit is literally doubled at 85% LTV, relative to the 75% LTV standard.It's possible that 19 of the 20 institutions you contacted concluded that it wasn't worth the reputation risk ("oh XYZ has horrible interest rates, they quoted me ABC" - without mentioning that it was for literally the worst interest rate pricing scenario that exists) associated with offering 85% LTV investment properties. 

Anyway not arguing with you just trying to learn of there is a better method. 

But on the flip side (playing devil's advocate) they might argue you should have a back up plan and have between tenants or rollover account or just switch the utilities to your name that AM (Friday) or a day early. 

@Mason CarterUsing Excel while you start out is perfectly fine.You have an option from your bank to export the monthly statement into excel.Once this is done create a column to the right of the transaction and categorize it.If the amount is a contribution, list it as a contributionif the amount is insurance expense, list it as insurance expenseIf the amount is a monthly mortgage payment, break it between principal, interest, taxes, insurance.You should be able to do a sumif formula once you captured all the transactions.Let me know if you try to set it up in excel and run into issues.Some investors will argue that doing your own bookkeeping provides little value(you are doing $10/hour work) while you should really focus on doing work that generates you $1000/hour(searching deals, networking etc).However, I think it's at least important to understand the numbers.

@Josh Huber I really liked "ABCs of Real Estate Investing" by Ken McElroy.
