like what most people don't get about the AI is that, currently, in 2024, the AI will become a sudden giant because there's world war three among data centre elephant and data modeler : microsoft vs google vs meta vs amazon, they are the one that's buying thousand of nvidia gpu with the hop one day that one small company or startup can replace the incumbent like google , pfizer All their purchase makes every single nvidia employee can buy a house in santa clara county easily lol. it would impact REI by a lot later on as employment and employability or group of persons would change.

Take a close look at properties that are doing well nearby and see how you can model what they are doing and then add some extra perks to beat those too.

If the builder never transferred title, they might try to argue that its comparable to selling a model home within a new construction developement (new home, but has had thousands of folks walking in and out for months...sometimes years).I would be confused as to why someone would offer it as new construction when it had been lived in unless their aim is to avoid capital gains, but you say lived in a few months and not two years so that does not track.

Our specific model is buy, rehab, rent for at least one year. 

Seems that I need to buy the 14 inch rough in toilets (which is hard, because only few models are available at Home Depot and Lowes, since this is a non-standard size).

And for sure sellers should basically never do them unless they are going to lose the property and they will get some equity by doing it and their credit is already trashed.. this was the model that i ran for all my sub 2 when foreclosure rescue sub 2 was legal in OR and WA. big times laws now..

The appreciation models only 3%-4% for SSF which is normal for 1 mil avg houses.Do not do ADU stuffs.

The financial model presented seems overly pessimistic.
