Ohio properties cash flow a tiny bit more for me.This is my personal experience with 6 properties, purely anecdotal

They take some technique or strategy that’s only workable or beneficial in a very tiny percentage of situations and generalize it as a major breakthrough.  

(Tiny old postage stamp lots)in parts of the bay area its mandatory to change the drain line when houses are sold if they are a certain age and still clay pipe.. my brother in law does a ton of them.. realtors are his source.. many times they just pipe burst.. and are done in a few hours for 6 to 8k. when I was doing my rental thing in the deep south we could get a new PVC from house to street 50 ft or so for 1500 or so.. if we did it during rehab and not under stress.. 

Increase portfolio by 100 units (a combination of a tiny home community in Florence, Arizona, a condo development in San Tan Valley, Arizona, a few multi-family properties and or mobile home parks, and 20-40 single family residences in Arizona and the triad area of North Carolina - mostly Greensboro and Winston-Salem).2.

The reasons for investing are much more than just cashflow, that is 1 tiny tiny part. 1.

@Cassidy BurnsMy wife and I will be looking to buy a home with a few acres at the end of year, and put a couple tiny house Airbnb’s on the land.

I am currently investigating how to have a shed/tiny home conversion or built on the cheap and think this idea has some real potential!

I can go buy 3 properties off the MLS that will maybe turn a tiny profit,  or could head over to Detroit and pick up 3 properties for maybe 10k each.... neither of these strategies makes me a smart investor.

Sold them all for a tiny profit but left unscathed.Thought I was done with real estate in general but ended up hearing about FHA and bought a 4plex locally here in Oakland with only $12K down.

As for seller fi, it's nice if they require a tiny downpayment of you, or it's a deal a bank won't finance (which i stay away from), but outside of those two perks I don't see a benefit to it.
