I agree with what you said in your post, maybe add management as you build your portfolio. 

@Kevin Kim Find the time and build your own lease.

My thought process was to use a construction loan to build a quadplex of about 4000sqft with each unit being 1000sqft.

They are not wrong, but restricting STRs isn't going to change that; building more affordable housing, on the other hand, just may. 

However, the other benefits of owning real estate are: - Taxes (depreciation/potential accelerated depreciation)- Appreciation (this is NOT always guaranteed, but over time, you will have appreciation)- Building equity (in this scenario, as long as rent is paid, you'll build about $140 monthly in equity)Please note some expenses that are missing from this are: - Management fees (8-10% on average, if applicable)- Estimated vacancy costs (2-3%)- Estimated repairs (5%)Disclaimer: I am a real estate investor and own four rental properties. 

Did not need to replace entire floors, just needed to replace from the nearest wall to that floor with a good contractor.

Does it take years to build a new construction and when does the mortgage start for those?   

I am a builder and I have some land and want to build a tiny home park. 

Hey David, I would say this largely depends on how many units you have, the age of the building, and the quality of the building/neighborhood. 

Hey mate,Sorry to hear about your troubles.I've been offering "true" turnkey properties for 10+ years now and have many scars to prove it.There has been and still is a huge stigma surrounding the industry and rightly so.The very best rated in the industry sometimes get blasted on the forum.Like with any business that has stood the test of time, we have had our fair share of successes and failures.We have done very well for many investors and could have performed better for others.Many times, we are to blame and other times it was the investors fault IMO.One thing I have always claimed is that we don't steal, cheat or lie and my team and myself work very hard and always make decisions with investors best interest at heart.Personally, I believe that folks that work hard and do their best shouldn't be crucified for an honest mistake when it happens.But, I guess others aren't as reasonable when it comes to such situations and I don't judge them for it.I take the punch on the chin and still continue doing my best.Over the years, I have made millions and lost millions but only blame myself when I loose.Not others.Also, I've always preached to start slow and only use cash which has cost my business 90% in sales volume.I just don't believe that investors should use leverage when first starting to build their portfolio.Reverse engineer and base all real estate, business and even life decisions from a risk analysis worst case scenario standpoint.If you believe that you can absorb a worst case scenario outcome, then pursue the opportunity.Build a strong foundation with cash owned properties and gain experience first."
