The OP would be much better off just doing a true FSBO......there are plenty of sites I've used, that charge a very low flat fee like $99.

"long term rental, medium term rental (30 days to 6 months), short term rental,"Not the OP but, how so? 

I would also mention to the OP that the IRS does state that use of airline miles is NOT deductible. 

I've done both, and every time i choose Coin op. 

This mainly boils down to the fact that if co-op is not listed on MLS then all buyers agents will have buyers sign an agency agreement prior to showing properties.

presumably they're looking out for OP. 

Read my first two sentences in my OP again...I'm not talking about ONE rental property, this was clearly noted.

I'm sorry I just ready OP again and saw its the Owner who lives in the basement.

I'm not really sure why the OP would want to do something that would result in a passive loss (that may or may not be deductible against other income) and active income subject to SE tax, but I don't know of any tax provision that would prohibit it.

Co-op or condo?
