I think building out a strategy and thinking about what you want to do moving forward is a great starting point because it doesn't seem like you have a shortage of options.From leveraging your existing HELOCs, opening a new one, or fully refinancing your property that is paid off, it feels like the biggest concern I would have for you would be 'paralysis by analysis'. 

The only issue is every one I've seen that match seem to not be worth it.The top 2 options look like land investing or whole selling. 

@Patrick Flanagan all of the above, but networking seems to be the best.

This seems to be what you need in order to obtain the preapproval amount you were looking for to continue to scale.

After some basic research, it seems to me that an FHA loan or, potentially some type of physicians loan may be the best option.

Town says I will need to install them but If I am reading code correctly it should only apply to new construction buildings over 4 units. https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXX/Chapter148/Section26iThey also don't seem to give specifics on what "substantially renovated is" But a court case ruling gave this clarification: “… in order to require the installation of sprinklers in an existing multi-unit residential building, the rehabilitation must be so substantial that the physical structure is rendered ‘the equivalent of new construction,’ i.e., in essence as good as new.

I know it might seem I am a little paranoid but I want to explore this subject and I cannot seem to find the right words to use in a Google search.... 

Account Closed The DSCR loan for properties that are stabilized and rent-ready and bridge loan for properties that need TLC or renovation seem like pretty stellar options for you!

Everything we look at here in Tampa seems like the numbers aren’t even close to cash flowing.

I'd also post in the marketplace looking that seems to work for lenders
