Both strategies have potential here, so it depends on your goals:Strategy 1 (Duplex) can be a solid choice for building equity and generating cash flow, especially in Austin’s competitive short-term rental market.

Encore, you would need a membership, if you purchase in the new phase (Spectrum ) they automatically come with the amenities (membership) included to your guests, but the HOA and management have other restrictions and all units come furnished with the same packages, so you can't make changes to have it stand out, which is what is really needed hear in Orlando since there is so much competition. 

All 3 parts are critical to being successful here and we’ve been doing it with todays prices, todays competition and todays interest rates.  

Do you know what a competitive cost would be and how I can go about finding a good and fair GC for ADU build? 

When you called, and it seems many did, the scammer answered the phone using my name (though I understand with a heavy foreign accent).

The only instance where it might be more beneficial to do it this way vs. getting financing right off the bat is if you need to be SUPER competitive with your offers in your market.

If you've got people fighting over your listing and competition trying to get into the unit, then you're too low.

You mean the water was so heavy that it cracked the floor joists and the entire floor and basement ceiling fell in?
