I wouldn't fret over her lack of sufficient notice.I would study your market carefully and get your rents up to market rate.

@Debra Leeson and @Leslie Pappas - if your job is relatively secure and/or your 401K balance is sufficient to cover any penalties and taxes in the even of a worst case scenario, this is quite safe - what in the world are you so worried about?  

FHA streamline is great for lenders because they get a shiny new government insured no-risk loan to sell on the secondary market with very minimal paperwork, underwriting, and documentation required, relative to every other loan out there (except a VA IRRRL streamline refinance), but for borrowers it almost always makes sense to cough up the extra paperwork to refinance into conventional with no mortgage insurance, assuming there is sufficient equity.Streamline FHA refinancing a pre-2015 FHA loan will save some money.

I'm not affiliated with them in any way, but I've seen the BP glossary and other sites and personally I prefer the clear, concise explanation - and especially the inclusion of formulas - that dealcheck.io provides.I'm still in a pre-first-deal phase of my REI journey, but I'm starting to create/customize my own spreadsheets and information cheat-sheets to have at the ready as I feel I'm now sufficiently informed to get off the bench and into the game.I hope you find it useful in your journey as well.

I recommend collecting sufficient information to make a sound and balanced decision, then take action.  

However if you plan on buying 3-4units, there is a trigger rule for FHA, it is called the self sufficiency test.

Contact your agent and see if your current policy is sufficient or if you need to add anything.   

Appreciate your tokens of wisdom around the forums, it's helpful!

Quote from @Elmer Wayne Fisher: If you decide to move forward, all you have to do is give the current renter sufficient notice so they can plan accordingly.

AirDNA is a very powerful tool that can help determine this, however unless there are a sufficient amount of 3 unit STR's in and around that area, I would take the numbers with an extra grain of salt.
