Does your projected cash flow include debt service and other expenses after the refinance? 

This is how bank originated debt works in the apartment scenario you describe: The lender collects their origination fees and debt service payments are then collected priorty every month until the loan is paid off.  

As an advisor who has written over a hundred IULs and own two myself, I can lead you to the correct way to structure these and show you what to avoid. 99% of agents aren't doing the best job for the client and this only makes their paycheck fatter.

We currently have 15 keepers, which is a great size portfolio while we have kids in school and college.  5 paid for houses will also do the job for you, if you have a pension from your service. 

They do get paid well but I have found I make more from other clients than I would from traveling nurses.

Consider that the other unit is paying or close to paying the debt service and you have little to no house payment. 

You'll struggle with the debt service at that rate after expenses on a property that size. 

However, I just tried to call the number you submitted and the phone number is not in service. give me a call or email so we can connect!

Or do you hire a pool service and roll it into the rent?
