So just because it's a loan on a rental property doesn't necessarily mean the interest will be deductible. 

I came across a question for our Rookie Reply podcast episode asking about property management software.

Investment Info:Office Space commercial investment.Purchase price: $1,100,000Cash invested: $25,00014,000 SF Downtown multi-tenant office building

I recently closed on a commercial condo unit (for retail), which is one unit in a building that also has 7 apartments. 

Again, this is with commercial/investment property; owner occupied or consumer loans may have legal issues rendering this technique non applicable.  

@Cole Starin sometimes it makes sense to sell the WORST property in your portfolio.Another option is why do a LOC on the duplex, when you could just do a $100k cashout refi to pay off all your debt AND keep the property?

The key is not the number of properties.

We don't want to bring on every owner or every property unless they fit within our target market, so, I do the far majority of the sales - this is our check and balance.

and what do you owe and what do you think the property is worth? 

For instance, the term could be 3 years and add a clause that says they have to return the property to the condition it was in when they moved in, not just keep their deposit.
