I believe the one benefits most besides the politicians are those low quality tenants that are hard on units, pay late, rough on the neighbors, etc.

The median home price is also very low nationwide which creates a low barrier to entry.

While you might find a lender offering low down payment options, you'll still need cash reserves for repairs, maintenance, emergency fund (ideally 3-6 months of expenses), etc.

Multifamily doesn't need any more pressure/demand since cap rates can really get low when too many people pile in, but I have to say that commercial real estate (including large MF) and other types of passive investing (mobile home parks, storage, etc.) can really make like much easier.

You have to buy very low to make any money on the project.

These low income housing plays are speculating and not investing.

Some of it is luck or taking advantage of opportunities (eg low interest rates). 

@Rishika Garimella I am a local home inspector and investor in the area. i think Austin is a sleeping giant right now. the rates are really scaring away buyers. but since competition is so low right now, its a great time to snag some property while its not being ripped apart by investors. i think the hutto manor area is a great choice, once that freeway opens up that connects taylor to round rock, it will definitely become a point of interest.

The risk for investors became low enough for them to be really interested in the project.

If you want to put down a low down payment, you might not cash flow for a few years.And FHA for 3-4 units is almost impossible.
