You made assumptions without doing any due diligence.

If my assumption above is correct, is it worth me starting out in an LLC or do I just keep it simple and buy in my name?

And of course the assumption is that you're buying your properties correct in the first place, to buy and hold through any storm. 

Purchase price: $75,000 Cash invested: $15,000 Sale price: $125,000 My first deal, I was 21 and had no clue what I was doing (and was under the assumption you needed to put 20% down).

I do not use rule of thumb or assumptions to formulate an offer or LOI. 

Pro-forma is very positive with conservative assumptions.

My assumption is the people buying my properties or properties like mine are in the same situation I was in in 2010 except I don’t think appreciation will save them.  

The savings is just a math problem that will depend on what kind of lights you are using, what your electric costs are per Kilowatt hour. if the sensors save you 1000 KW per month at an assumed cost of $0.12 cents per kilowatt hour...should save you $120 per month....no clue if those numbers are good assumptions.

Post meeting Update:Owner corrected my initial assumption that the property has a single meeting.
