One lesson I have learned over the years is that some types of debt are not bad, as long as you are earning a reasonable amount of cash flow.

@Anthony MikolichThere are several banks that do HELOCs on Investment Properties.The one that I know is East West Bank: East West BankI understand there are a lot of suggestions to do a refi, but there are two problems with that:1) That's not what the OP asked and 2) There are REAL reasons why to use a HELOC... which is why it's a Loan Product that is available.HELOCs give you another choice to use money temporarily and is better than HARD Money.I will wind up getting huge discounts on properties with an All Cash Offer.The discount I get can be upwards of $100k on a $1.5 Million property.BELIEVE ME.... it is worth it.

There are a lot of different reasons why it may not be possible.Must be owner occupiedOn properties over 2 units, FHA has a self sustainability requirement. 

Keep things the way they are now and with all new tenants.Send out the proper notices allowing yourself sufficient time to replace tenants that for what ever reason choose to move.

I would throw a "caution flag" by saying that there are still good management firms that are not NARPM credentialed.The reason I say this is because there are minimum unit requirements (500-Unit Years of experience acquired over a minimum of five consecutive years) that quite frankly plenty of PM companies will never hit.

I do interest only for DTI reasons. 

Then MEH, there could be a hundred reasons from the verbiage never transferred across some internet site, to the listing agent forgetting to add it, to the guy having not done anything with his license in years and just remembered he has been paying the $50 every two years to renew it with the state, but hasn't belonged to the board in years.

This is one reason Partnerships are over rated.

In MD they are freely assignable and we often move them from company to company for internal reasons.
