This can range from a few thousand to several hundred thousand dollars, depending on the complexity and size of the project

IDEALLY, we would like to find a property that has or is capable of being converted into a “mother in law”, “ADU”, “Casita”, or any other separate living quarters in which we could rent out the main portion to a tenant (short term or long term) and then use the separate space as our own for when we come and go with business.

If you’re planning to pay cash for the rehab, make sure the lender provides non-dutch interest on the rehab portion so you only pay interest on the funds you actually draw, if any at all.Once the renovations are complete, you can do a cash-out refinance after 3 months of ownership.

I have an opportunity to purchase a 2019 built 6 bed/6 bath 3300 sqft (Pool/spa, media room, full size garage) fully furnished STR in Encore Reunion community @ 180 per sqft costs me 600k.

I see this home and what you paid and while it's not at all a bad price, I've seen investors offering that size in Palm Bay for as much as $15-25k lower.

This is not a once size fits all question IMO.

Hey @Kenneth LeeIn my experience, loan size alone is irrelevant.

In fact if you don't do proper due diligence some are "traps" with bad layouts, fire damage, and tiny sized lots. 

It does not matter the size of the city. 

Most people focus on the numbers and then learn the rehab portion through trial and error/ feedback from other investors.
