I think you would also need to check your local laws about normal wear and tear as I know in the cities I do business in, I could ask that they limit nail holes, even make it a lease term, but it would likely not be enforceable if they did it, anyway, unless it moved beyond normal wear and tear, like leaving a huge hole from a TV wall mount or something.  

Amy,I've not used them with steam heat, but have used them with hydronic (hot water) systems - both the old-fashioned wax-plug/mechanical kind and the newer, electronic types.Many of the newer electronic one allow the the use of a remotely mounted thermostat and some can even be programmed for set-back times (i.e. during the work day or at night).When compared to manual radiator valves, and the humans who will not remember to adjust them, either kind of thermostatic valve will save you energy and money, but the newer electronic ones with remote thermostats/sensors and, optional programability, will save more.

If you are looking for that price point and a cash flow property look at markets like Fayetteville, High Point, Burlington and Rocky Mount.

I want to replace the ugly ancient cast iron radiators with modern flat wall mounted units. 

Typically, initial contribution is some de minimis mount to get the bank account openned where each of your put in your % of ownership.

@Aimee Sowards-Mounts is correct, there is only a certain subset of mortgage lenders that work with OHFA.

He is destined to lose this as long as James fully mounts a defense. 

Places like Kitrell, Wilson, Rocky Mount, Roxboro, Sanford, Oxford, and towns with a similar radius are all interesting places to consider. 

@Aimee Sowards-Mounts, I currently invest in Ohio and am interested in Columbus!

If you want to go East of Raleigh to areas such as Goldsboro, Rocky Mount, Wilson etc.
