Hopefully, based on actual field measurements, past project data, and estimating software, your contractor can develop a detailed estimate that lays out the cost of labor and all materials for each phase of the project.

There's definitely a few things to note since you are residing in Europe, most of the investors we work with that live over there do put it in an entity but there are a few details for how that would work since you aren't necessarily local. 

(August 2022)Single-family residence buy & hold investment.Current Value Estimate: $410,000 Purchase price: $345,000 Cash invested: $5,000

He get's principal and simple interest payments over a number of years.I'll manage the deal and the property.Looking to create a proforma for this that would fit a typical rental analysis but insert the detail of having private money cover the DP.

As we evaluate deals, we're wondering if we're being too conservative with our estimates.

Each grouping had a common room (perhaps it was shared by multiple groupings ... this was a detail I missed) with a nurses/aid workers office.Central to the two sides of the complex were common facilities such as a dining hall, gym {perhaps a pool ... another detail I missed}, theatre &  games room.With one of the fastest growing groups in our society being single people, we are examining a related idea of a  complex / building providing a modest-sized 1-bdroom "apartment" with more semi-private and common amenities.When I read the title to your thread, I thought it was a project proposing to mix students and seniors into a single complex ... and came in thinking, this ought to be interesting :-) 

I love the more detailed analysis but I'm overwhelmed. 

With that information, you can start to get good at estimating the rehab budget.  

None I could say with confidence without knowing more details on the borrowers experience, property type, city, and project numbers (PP, Rehab, ARV).

In my estimation it takes 2-5 years before a rental is broken in and feels like a good investment.
