OK so update time:
I ended buying 6 properties in Indianpolis. 2 SF, and 4 duplexes in C and C plus area's via financing. Started April 2016 and bought last property in Dec 2016. Spent about 143k total after doing some moderate rehab. Cash flowing about 2,700 monthly after accounting 20% for repairs and vacancy.
Positives: Cash flow! See above. I think I did pretty well. I am nearly at about 23% cash on cash return. Need to buy more, but stopped as of Dec 2016 as I actually took the plunge and bought a home in bay area due to fear of being priced out. These double digit year on year price increases will do that, and I refused to do a long commute. So now slowly starting to build a reserve again.
Lessons learned: My realtor didn't give me a good indication of how much rehab costed when I purchased, so it took about a year and half to start making money. Essentially I used my own cash and most of the rent money to pay the reno costs.
Also communication and being patient to find a tenant is also key. Better to wait a few weeks longer or a month to find a good tenant, or even lower the price as I had 2 tenants that were very difficult and caused issues.
Turnover costs have been minimal so far. I had two, costed just a few hundred dollars and rented within a month.
Hope this helps!
