@NickyReady  Have you considered an installment sale?

Like Arsen, I removed all washers and dryers from in the units and installed coin laundry in a common area (basement or common room).

I know Carpet is a lot faster to install. I

You can also hire out the work but if you don't understand what can be done and how to do it, you usually end up building your custom software several times and the ROI goes out the window.There are some good off-the-shelf solutions as mentioned though, which is a great option if you don't want to DIY. 

I am doing some renovations to one of my units and I am going to be installing a washer and dryer in the unit so they do not have to share with other tenants in the building.

Most of my owners were DIY Landlords before hiring me.

The 179D Energy Policy Act gives taxpayers a deduction for installing energy efficient assets such as the building envelope, HVAC and lighting.

Educate yourself in using Options, Leases, Sub to purchases, Master Leases, Land Contracts, Installment sales via a note and mortgage and you may realize you do not need banks to build a portfolio at all.

@Dave Foster thanks, I'll check the requests.Do you or anyone know about Structured Installment Sales? 

If your seller financed the deal, you need to report this as an installment sale.
