Per this NY Times article, the average American knows around 600 people.https://www.nytimes.com/2013/02/19/science/the-average-american-knows-how-many-people.html#:~:text=The%20average%20American%20knows%20about,do%20you%20know%20named%20Kevin%3FPer the US Census Bureau, the average American moves 11.7 time in their life, which based upon an approximate lifespan of 84 years, works out to be about every 7 years.https://www.census.gov/topics/population/migration/guidance/calculating-migration-expectancy.html#:~:text=Using%202007%20ACS%20data%2C%20it,one%20move%20per%20single%20yearSo, if the average American knows 600 people and they each move about every 7 years, that means that the average American knows around 85 people that move in any given year.How many of those moves do you want to be involved in?

If the bill is $100 a month split between four units, increase it to $120 and charge each tenant $30.How to calculate charges.

Just taxes will be 20k.I would run numbers like this:Property 1.5 million (minimum)Construction (Cheap end) 2.14 mHolding Costs (at least 150k)In my book, even according to your calculation, that means you put in at least (those numbers are on the low end): 3.8m! 

I ran my calculator to get a quick "what if" on a 30yr picture.

Also it's good to research how the municipality calculates property value.

Basically you find these distressed properties in pre foreclosure, probates, divorces, or just ugly vacant properties. then you calculate the Max allowable offer and if it makes sense you call up the property owner, get it under contract for dirt cheap, then you assign the contract to a cash investor for an assignment fee. this is the general idea obviously it gets more in depth, but its finding deals that you would buy as a fix and flip or brrrr, and instead of actually buying it you sell it to other investors.Ahh I see, thanks for clearing that up.
