I have done it successfully on my last 2 buildouts, maybe 3, but only because I was able to acquire the properties at a very low price and I did all the work in-house (myself and some hired hands on staff).

-how many bathrooms per resident have you found to be successful?

There are hundreds of thousands of people in this BiggerPockets community who are very successful at real estate investing and are willing to provide you with the same information as these guys, but for free. 

Four properties were existing STR's that had a permit 'transfer' and the other half were eligible properties that successfully launched with astounding success.

It seems this investment was incredibly successful for you, but the resale is most important.

They love the nostalgia of it and wouldn't consider replacing such an important and historical thing.There is no script that will lead you to success in this, but friendly and collaborative will help.

No offense, but hire a PMC because:1) You hate the process of placing tenants.2) You didn't do a very good job of screening the current ones.Sometimes we have to get out of our own way to find success!

How did you find this deal and how did you negotiate it?

I invest in Boise, ID and do quite a few BRRRRs, LTRs and STRs- varying degrees of success depending on how much equity we can force and the type of back end financing we can find, but the tax benefits are great and it's a rapidly growing market and Idaho is probably the most landlord friendly state in the nation. 

Because the chances of successfully concluding a wholesale transaction when you lack experience, knowledge and capital are so infinitesimally small that you’d be better off playing the lottery.
