These Buyers don’t have the best credit but they have cash for down payments, and make monthly payments. 

A few that I've gathered so far:Will a portion of rent go towards down payment?

Buyer puts down $200k and makes payments.

You can use the costs of classes on a down payment and the time in classes can be used finding properties.All my high net worth RE investor clients don't use their degrees at all.

Increased rates makes it more difficult for first time buyers because 1) the financed payment goes up 2) it decreases movement which results in boomers, etc not downsizing which lowers volume on the market and helps keep the prices from falling.Other drivers for these large rent increases are the recent property appreciation (last 10 years have had huge RE appreciation) and rents lag the property value increases, the Covid eviction moratorium has identified new risk that must be reflected in the income, the continuing trend to move to high growth areas which results in a large housing shortage in these areas, the lag of new housing starts that has existed since the Great Recession.  

You should look into finding a down payment assistance loan on your primary house.

@Alex JacobsBuilding a rental portfolio through house hacking is a terrific idea, particularly if you want to reduce your down payment and increase your income flow.

I am a newbie landlord looking to streamline payment, maintenance requests, background checks, etc.https://www.azibo.com/

First, I could use that for a down payment and renovation for a second house to rent it out on Aironb or long term tenant. 

Replace matured or payment default loan with loan of greater amount and pay off all arrears3.
