You essentially have essentially cast a super wide net and are going to get a ton of sales responses, but what I gather from your post that what you really need is a mentor/like minded investor to help hone in on recognizing good deals, narrowing your focus and absolutely protecting your capital.   

Typical bridge loans offer anywhere from zero to two 12-month extension options, but this can vary widely depending on the specific lender and deal characteristics.

That all being said, I really don’t think open concepts or great rooms where the kitchen, living, and dining areas are either wide open or visually connected is going away at all. 

In addition there are a wide range of grants HUD supports in most cities to improve a property to rent to low income people.Perhaps the best decission in looking at section 8 and low income rentales are the larger assets of using the contract incentives and special financing programs that only exist to those who provide services and employ your tenant that you could benefit from.

I'm interested in talking to someone about getting our nonconforming basement up to code to either duplex down or make it a legal unit if ADU ordinance passes city-wide.

Wall st vs main street is wide, and it's going to get wider before it tightens. 

You can earn from the many contract set asides, tax incentives and specialized financing  that exists only because of your tenant.My funding group (DTRT FUNDING & Consulting - Do The Right Thing) funds what we call the path.. all the varisous companies and non profits that can benefit from the wide range of tax, contract setasides, funding and income generaded by that trnant becomming a productive and independant person.Would love to talk 

It is not small, it is a very long and wide beach.

Going outside the city limits is a good work around that works in markets that don't have county-wide regulations.

But until then I agree with you, that's not a growth strategy.I am a firm believer to grow your portfolio first wide, before you grow it deep.
