As you mentioned: it will be hard but not impossible to find the right deal-- something you should bear in mind also is that when you are looking for 2-4 units with FHA, duplexes have to pass less "tests" to qualify your financing and are typically easier to get into.

For example, 4th of July week, Bear week and Carnival I got $4,000/week for.

Headers in load bearing openings were also often undersized for today's heavier loads causing sags in openings.

An orchard or a vineyard is a systematic planting of fruit and nut-bearing trees or grapevines as opposed to individual plantings for ornamental purposes.

He did an inspection when I took out a load bearing wall and ran some new outlets and lighting circuits,  didn't have any issue with me doing all that myself.  

My only question would be are you open to implementing the BRRR method with this duplex or are you looking for something move-in ready?

Bearing those things in mind, maybe a gut rehab wouldn't be a bad idea. 

I could be giving advice based on my years of investing in Mexico and the Riviera Maya and helping many buyers and investors do so but I won't because I have no fiduciary duty towards you and you're going to be the one to bear the consequences.

Not sure if that has any bearing in my situation.  

I spoke to three companies yesterday and they looked up soils maps and they believe our cost is going to be somewhere around $20k-$25k, possibly up to $35k if we need a special system.
