My focus is on affordable housing, especially mixed-use projects that serve both residential and community needs.

Single-gender homes are only for transitional housing (like soberliving houses, halfway houses, etc). 

Attend open houses to understand market trends.

Try looking into cities in with stable economies, strong renter populations, and where housing is below the US median value.

@Jason Sinclair, having a designer for a wife, I would answer that it really depends heavily on each house, the flow and usability of the spaces as they are, and the overall use of space in the house as a whole.That being said, while there may be a small shift towards more separated spaces, "open concept" is by no means dead, and in many markets, most people seem to still want to have connectivity between their communal spaces.In fact, my wife's current flip is a split level (although technically it is a split-foyer), and she is taking out a structural wall to connect the kitchen, dining and living areas.  

Which options do you guys think are best when you have no money to put down on a house for flipping?

This works best when the seller is motivated and open to flexible terms.4.BRRRR Strategy (Buy, Rehab, Rent, Refinance, Repeat)– If you find the right undervalued property, you can finance the rehab with short-term funding and then refinance into a long-term loan, pulling most or all of your money back out.5.House Hacking– If you’re open to living in your investment, you can use an FHA loan (as low as 3.5% down)to buy a multi-unit, live in one unit, and rent out the others.

I've dealt with this exact same situation, and ontop of everything I was dealing with the Section 8 housing authority because my tenant was a voucher holder. 

You can buy a new house every year or pay your 8% down.
