Thank you @John Mason.Do you have personal experience with this firm or some you know is good and reliable ?

You are looking to rent or buy a space with a partner to have a personal fitness business or just a class?

I would recommend choosing someone with the most forum posts and/or reviews that way you know that person is active 

Since, you will have to do business with them on your properties on a personal level.

Buildium has this statement, hopefully your PMC knows how to generate it.You should be able to give your tax professional the 1099 and annual statement, along with property tax, insurance, etc. bills you personally paid and that's it.I think Buildium even allows the annual statement to be sent in CSV format, so you could just add the expenses you paid to that.

A great way to network and meet people in your local community is to attend in person meet ups.

I personally use this for my biz and know of many folks who have cold calling service using this.

It's similar to how you report it for tax purposes in years where you aren't selling it, you report 50% (or whatever % is allocable to each side) as rental property and depreciate that 50% while the other 50% is your own personal residence and therefore is not part of Schedule E.

If you're comfortable meeting in person, I would follow up with an email outlining what was said in person to the tenant with the resolution of the conversation also in the email.

Last year we were able to connect an investor of a coastal six plex with our personal credit union and due to strength of borrower and property, they provided a non-member with a 25% down mortgage with a 25 year amortization on a property the seller was requiring 'cash only' due to the presumed challenges of multi family financing.
