First pro is you learn how to be a landlord and to manage properties and this is the best way to get started into real estate investing.

Best of luck in your real estate adventures.  

The bank will make you leave 25% equity in the property - but you also still want the property to at least cash flow some - so be careful how much equity you pull out / new debt you take on.I would do a cost benefit analysis of what your actual gain is in cash-flow on buying a new property with a (currently) higher interest rate (if financing), versus just holding on to the current appreciated property and enjoying that cash flow.All the best!

I’ve been manually scouring Zillow/MLS for deals, but it’s time-consuming, and I’d love to streamline this.2.Has anyone experimented with using machine learning models (like classifiers or regression models) to rate properties based on their condition from MLS listing photos?

That moratorium is supposed to be temporary.Mind you, while the US used to have (some of the) lowest interest rates in the world for the last 15 years, this is no longer the case and the US actually has some of the highest interest rates in the world nowadays and that doesn't look to change any time soon.

Considering a rate buydown on a DSCR loan?

Quote from @Mackaylee Beach: I think these times (the last two years), and this year are the ones that will give birth to some of the best investors.

However, with high rates, the next mortgage would be very expensive, and a vacancy would be intensely expensive with two mortgages.

B class will be basically break even maybe slightly positive cash flow on a good deal with your typical 20% down payment and financing the rest with todays interest rates. 

You will find rates all over the place just like with all insurance.
