If the latter, simply give her the notice required (eg 30 or 60 days) that she needs to move. 

I think a HELOC requires a certain LTV before you can pull any equity and 1 year most likely won't be long enough for any real equity to build.I would say.

I would recommend targeting 30 day minimum rentals (Most associations are 90+), allowing 12+ rentals per year (most allow 1-3), and no in-person screening for tenants required.

I understand Costa Rica may have different requirements, but $600 sounds steep and having to do it every year seems excessive.Thank you to anyone who can give me some advice.

@Kyle Trotman If you purchased with a hard money loan conventional lenders will require extensive seasoning to utilize the new appraised value for cash out. 

Am open to single or duplex property that is requires minimum or cosmetics renovation.

These are all important considerations, and understanding the requirements can save a lot of headaches down the road.

It may require more work, more analysis and more time, but if you can find one great passive investment, I bet you can find 5 or 10.  

This isn't always the case, but in general, I've found Section 8 homes tend to require more frequent minor repairs.

Multi-family properties many times provide a better return per square foot than single family, which would be to your advantage as well.As long as you're mindful of the reinvestment requirements and purchase at least as much as you sold and use all of the proceeds, you shouldn't have any issues with this strategy.
