I would highly suggest getting a duplex, triplex, or quadplex for your first home and house hack it by living in one unit and renting out the rest. you can get in it since its your first home for quite a low down payment. and BOOM!

Remarkably, despite these ongoing shifts, delinquency rates remain low on a relative basis when compared to the office, retail, and hospitality sectors.Although factors such as declining household formations, rising supply deliveries, and weakening demand may present temporary obstacles, the sector has successfully emerged from similar challenges in the past.

If you are trying to sort out which local PM's operate in low income and Section 8, I would look at whatever marketing mode is most prevalent in your area (Craigslist) to see which PM's are advertising those types of properties. 

Mortgage rates are nowhere near 4% due to FED rates, treasuries, and MBS currently so unless this is an "Angel Investor" it's not possible to be that low.

Many cards offer a low rate for the first 12-18 months.

@Andrew Hale I would say if you front load the amount of time you spend on your real estate by spending extra time doing your research on your location and the neighborhoods and the type of investments you want to do that can make all the difference for you.

But in your neighborhood. 

Anyone built new construction specifically for Section 8 tenants, or similar situations where tenants are low-income, but rent is somewhat guaranteed by vouchers, etc?

I really appreciate it.Based on this, I would try to keep the original home with a low rate like that.

The previous month, Yellow sold a 9.8-acre truck terminal, which included a 38,000-SF industrial building, for $80 million.Price discovery is underway after years of outsized rent growth paired with low interest rates drove robust appreciation.
