It takes time to develop trust and credibility with potential investors, so don't wait until the last minute.

Network with local investors, undertake extensive due diligence, and develop a clear exit strategy.

The first indication is you spent $290k for $1800 cash flow or a 0.62% monthly ratio.Rent $1800 - PITIH $1480 - $180 (pm) - $90 (vacancy at 5% which is lowest i ever allocate in my underwriting and likely low per the OP description of a lot of new development) = $50 for all other expenses.Maintenance/cap ex on 4/2, 2100’ will exceed $300/month even in cheap labor markets on sustaining basis.  

More like  2X to 5X the cash out.. these are done with builder developers on their deals So put out 300k get 300k back in profit plus the interest rate. most small builders/ developers need to have a equity partner so you just do both you lend the money and are the equity partner.. pretty clean..

(FYI - this was an SB9 "two unit development, not an SB9 lot split). 

Hopefully, based on actual field measurements, past project data, and estimating software, your contractor can develop a detailed estimate that lays out the cost of labor and all materials for each phase of the project.

The primary goal is appreciation adding value building equity and therefore net worth.I’ve been at this “game” 46 years  and there is no magic bullet.It takes time, discipline and consistent effort.But it can be done in 10 years.Of course this means living below one’s means - ie spend less than they make - to develop and build cash and capital that can be invested and then watch ot grow over time.Hope this helps.Arn

Our primary objective as coaches is to help clients ask the right questions, develop the right criteria, and identify potential red flags. 

To be owner builder without hiring a gc you will first need to have 3 completed in the last 36 months or can just developer rather than owner/builder  I'm not currently at the phase of transitioning into a home builder, more trying to learn the steps of how to better set myself up for success.

I have no idea how anyone makes money investing in real estate in the Hong Kong market - other than developers, that is.
