The worse the condition and appearance the lower the rent the property will command.

rural smaller towns in IN you have to be careful as well  and again you want to buy where you can command 850 to 1200 rents.. buying in these markets and having rents sub 700 is just asking for trouble IE consistent cash flow Also if you want to take the time look at the recent Morris invest thread.. all the top turn key companies chim in on why 40k turn key is not sustainable or advisable.Its one thing for you to BRRR them .. buy doing that your probably into the home at least 10 to 20k less than buying it from a rehabber that did all the work for you... so you can move up in quality both in asset and tenant.

I think it's all about seeing what's happening in the 5-10 block vicinity of your property, and waiting for the trends to tell you what to do or not do to command more rent.

You are most likely not going to be all in on a property for $50,000 and command a rent much higher than $500 - $595.  

Self storage is pretty saturated here..My experience has been 4 plexes cost a little more per ft to build than the larger complexes but they command a little more rent.

Let's suppose you fix up a kitchen (or some other thing).Let's suppose that will allow you to command $175/month more in rent, and let's suppose you have a vacant month each year, normally.Let's further suppose that it will cost $10,000.

The best districts always command a good demand.

Given your highly desirable scenario, in a great California market, if the loan were at 8% what kind of price would that seasoned loan command?

And this was a retail purchase right off the MLS.So, why would someone purchase a property for $100K that needed a $30K renovation and was maybe worth $110K-120K  as a flip or only command $1250 per month as a rental? 

Rentals on Zillow and Craigslist) to see what the market commands.
