does anyone know of a general formula to determine multifamily insurance cost per unit?  

If you want to live a bit higher on the hog and buy expensive stuff, get 15 or 20 or a few more, but do it with the same formula as above.You don't need 100s of houses.

maybe Google just doing this like they did with Google Flights to leverage their negotiations for higher advertising dollars from VRBO/AIRBNB etc, like they did with Expedia/Hotels.com/United/Delta etc and they have no real interest in making it a discrete profit center but just a strong profit stimulant to their core advert business.buy more Google stock usually a winning formula last 20 years

Markets are very important, while most rents have slowed, some markets a lot less than others, and the better markets will rebound quicker.If we go back in time, this song has been played.

@Randall Alan that is the winning formula. 

After the second one, could the same formula be repeated to own 4?

They handed out new debt at '18' rates "saving" the business's and all they could do and "save", ooohhhh how we should sing song's of these great "saviors" to us all.... and ignore that they did it with OUR MONEY, consolidating trillions in business that had been compiled over decades of effort by hundreds/thousands of business, all unto 1 national to-big-to-fail goliath.     

.🧮 What Is The Cap Rate Formula?

Obviously, the more you borrow the less your Amount Invested is in the formula above and the higher will be your ROI.

This is the first time USA is acting like Africa fourth-world country that they blocked presidential candidate by using a "judge".Also take a look at how Elon Musk is treated when they're not voicing the same song as the elites.Something really broken in America.And, in this digital age, with TX now the 8th largest economy in the world among nations, does TX really "need" the Federal Union any longer?
