This strategy is something I developed during Covid and have stuck with since I rarely found success with the in-person group networking events (likely my fault, not the events').

Builders of single family homes in a development are usually building to sell them to homeowners, not rent to tenants.

There is a lot of growth and development in the residential sector but there is also a huge amount of growth in the industrial sector as well.

There are at least 20 developed countries with lower interest rates. 

So much development in 7 short months. 

I'd like to develop a solid business plan but to honest I'm not sure where to start or what all to include in a well formed business plan.

I would first say it depends on how many properties you wish to purchase, the size of the properties (land square meters) and which area/zone you plan on investing, and if you plan to take on commerce and labor activities such as building and developing.  

Here are my thoughts: Cons:- The developer takes most of the margin (Expensive).- Limited upside (no sweat-equity)Pros:- No improvements are needed.- More longevity (Easier modeling of CAPEX)- More lucrative/easier to rent.Did I miss anything?

I'll need to find or develop a decent spreadsheet for cost estimates now. 

A local developer who had his fingers in many pies and was known to be fair and to do good work, said he had a garage behind an apartment building for rent.
