I am looking to try and build up funds to start purchasing properties.

Check out NOWi Sensors They have building monitors, toilet monitors, flood monitors and they focus on multifamily.

For clarification: you have a first mortgage and a second mortgage on this new build?  

Again 20-30% is fair.I have an almost 100 year apartment building where I pay some of the utilities. 60% is a fair estimate and it's often more than that.I have a couple of older houses in 'bad areas' where the tenants regularly trash the property causing thousands of dollars in damage and move out in the middle of the night.

I work with a company specializing in building Tiny Homes.

@Ryan Corcoran I would definitely recommend connecting with Delta Build Services, happy to send you direct contact information if you're interested!

Financial Transparency:Managing the budget yourself allows for greater transparency in costs, helping you to identify where money is being spent and find opportunities for savings.It's important to consider the potential downsides, such as the significant time commitment, the need for substantial construction knowledge and experience, the risk of costly mistakes, and the responsibility for managing permits, inspections, and compliance with building codes.

Detroit is literally a block by block city and if you are not here to see the property you need boots on the ground that you can rely on to assess any potential purchase.  

Are you building targeted lists, calling them with a correct script, trying to build relationships? 

BUT I think you are playing with fire.My primary job function is outside sales building relationships with realtors.
