-option 1 has lower entry costs since the beachfront properties can get very expensive (anywhere from $2/sf up to $20-$40/sf)-construction costs in US are considerably higher…$120-$140/sf vs. $75-$80/sf overseas (high quality)-loan service costs are cheaper in US vs overseas…-reselling in US is much easier vs overseas-maintenance people, managers and operation costs are way lower for option 2I know that these are very broad different scenarios with a lot of variables…however I am trying to see if I can get some feedback.

If you're a decent contractor, you may be able to partner with someone willing to purchase the house, if you can front the construction costs?

There are currently a number of software options that are being geared to contractors for remodels and new construction - which translates to rehabs. 

I know my comps and my markets very well, I have a great construction ability, and I sell well, so my comfort level is based on my personal experiences with real estate, and my personal expertise...

I have a construction management background with management/sales experience.

I wonder if I am working too hard to make this solo 401k a reality when the IRA-LLC construct is a rather close second. 

I had a construction budget of $85k.

@Jose L Aguilar Are you asking if you should buy older homes or new construction?

I am in the Los Angeles Metro area - I have experience investing in SFR from Cosmetic to New Construction.

I'm currently in school for Construction Mgmt. at Kennesaw State University (Go Owls!)
