If the home was a single family their interest would still be protected values in the areas are up.

Since you said tiny homes, this is probably not an option.  

I've mainly looked at Home Depot/Lowes for flooring and larger items and got hardware like knobs, faucets from amazon/wayfair but curious to hear where you all get your materials fromAlso, need to get a double vanity for master bathroom, any recommendations?

You can buy an almost new or brand new single family home here in Arizona for $250-300k, combine taxes and insurance of under $2k per year, rent for $1500-1800, will break even on cash flow with 25-30% down because there is no maintenance or cap ex since it's new (you will have these eventually but rents will increase by the time that happens).

Buy a solid home, in a solid location where you can break even or cash flow a little and that will appreciate well over the long-term.

tag=slickdeals09-20&...I have never used this one as I am a pretty firm believer in the Zinus mattresses but I just ordered this up for our primary home.

The reason for selling is because the home has been a money pit (major tenant damage) and a revolving door (tenants leaving).

we currently live in long island, and was thinking of upstate NY, as that would be a drive away, if we ever decide to convert the STR to our vacation home.

If you buy the "on sale" office building, it will cost some money to convert, but if the savings is there on the initial buy price to more than make up for it...And then let's say 5 or 10 years from now the "work from home" fad is over and offices are in demand again.
