Further enhancements included constructing a back deck and repainting the interior to modernize and enhance the home’s appeal.

Build sleeping pods that are mostly soundproof (double walled construction) and ventilated. 

I have 2 options:- finance the construction pre-selling the apt, and take my profits (expected to be around 700K pre-tax); or- finance the construction with a 6-7%/year loan (collateral = my house), keep the 10 units, and once the building is completed in 24 months, rent them for circa 180K/ year gross.

Numerous times I have been able to think through an issues that arose on a construction site and saved the Owner by proposing an alternate route to resolve it.

Alternatively, you could consider seller financing, which could provide you with a steady income stream while selling the property.As a real estate investor, realtor, and owner of a construction company near Texas A&M (College Station/Bryan,) I'm happy to help in any way I can.

This information is then linked in the database—think of techniques like pulling signatures from mortgage documents and extracting unit counts/construction types from building permits.This allows you to search my name and instantly see all of the rental properties and construction projects I own, even though they are well covered by holding companies.

@Robert EllisAre you leveraging construction-to-permanent loans or private funding?

Additionally, I would like to attempt to do the process Owner/Builder with subcontracting work out as well as doing some of the work I'm comfortable with (I have some experience with bathroom & kitchen remodeling an am not new to the construction industry).

Can someone walk me through the thought process I should be using when constructing the offer?
