Recent zoning changes now allow for three dwellings on a single parcel, and parking requirements have been lifted in denser areas, both of which have boosted the local housing supply.

Construction is mainly CMU, Concrete, and Steel (at least for my projects), and there is a bottle neck of those resources as only few supply the area.

Consider cleaning, lawn care, snow removal and supplies as well as utilities  in your calculations.  

I already had my own business, some cash, lines of credit and a solid contractor as a partner which is how I have grown my portfolio so aggressively over the past few years.Unfortunately, $8k is not going to get you very far despite the promises of no money down investing.

US unemployment near all time lows and GDP stable so that means FED FUNDS rate is not constrictive so they may not need to cut rates for years, and US GVT spending quite a bit more than willing to tax, so long bong Issuance going up (2 trillion issuance projected this year) so more supply = rates go up =CAP rates go upCapital Calls seem very likely Even if rates drop, those occupancy levels are awful.

List the property on MLS or with a trusted real estate agent, and market aggressively through social media, local advertising, and open houses to generate interest.

Add on rollers, tape, floor coverings, etc and it could easily be $300+ in supplies. 

Take that away by making it clear you will pay for, even supply, all materials. 

The easiest thing to transform them into is storage unit places but there is only so much of that before you have an over supply.

As far as ethically that is part of my nature and I don't care for the aggressive (potentially predatory) strategies discussed by others, but I see value in offering a transparent and convenient service with lower costs and faster turnarounds than traditional MLS transactions.
