Not sure if you staged it, but I did my homework early on when I first started so I know my pricing and I build it into my deals.  

The issue I take with anyone looking for an app instead of building their own is that it misses the forest for the trees.

The only exception is for on-site managers, like you'd find living in one unit of an apartment building and managing the building on behalf of the owner.

My suggestion to any one that are first time real estate investor in fix & flip, or planning to hold property for rentals, is to learn or read, understand about real estate financing first, build your assets and network or partner withsome has completed some projects in fix & flip and has some rental properties with positive cash flow within your immediate area before dving in to any project by youyrself.

The latter would create mortgage rates issues, the former will eliminate a lot of fake demand and some material real demand in the housing market that is bid side.Mortgage rates higher + build costs higher(less labor + tariffs)= Kill demand.

Her husband is also a GC who can help build additional units as needed if you get something that can fit an ADU.

Also, the ability to find good deals with an accurate budget to complete the project up front from some good project managers/general contractors.

@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

Really just trying to build a solid base and gain as much knowledge as possible and eventually specialize in something.  

This is very useful.You could build a deck or gazebo to house a hot tub.
