I think bringing a design expert to run through these properties with the contractors and put together the design based on a specific budget would be a good idea.  

I’ve built my own SF, MF and designed STR and have been successful within all three but they all take work and risk.

Yes turnkey means the GC handles everything from permit to CO and gives you a turn key guaranteed price that does not change unless you make changes.Also some GC have stock plans or do design in house which will save you on design fees.

They typically have a "designer" or "consultant" for free that can give advice (or research in your case) specific items.

And the tenants are generally very pleasant to work with.When I worked for a construction equipment manufacturer, we designed a brand new line of skid steer loaders and what we found was that all the profit came from the large machines.

The answer is clearly yes, not to be fair the 2010’s were probably a golden age for re investing, this is an especially tough period, so that gap feels huge, some of this is just a result of the pandemic and subsequent inflation, some of this is by design, the Fed wants to restrict investing and for you to put money into tresuries and cd’s not real estate & stocks.

We are getting a decent deal on the property and essentially being gifted 20% equity of the property. 

Thanks @Travis Moe unfortunately the zoning designations of "multi-family, single family, other residential" isn't granular enough for me (I need the exact zoning).

From favorable lending rates to tax benefits for homeowners, these policies are designed to encourage buying and selling activities.

By design the bridge loan in most cases will only be held for a short time.
