After accounting for closing costs, you end up with a very slim margin.I have noticed that a fairly large proportion of the investors here have their own real estate license so they save on selling costs.

This is deductible in proportion to the % of your home that is used as purely a rental (the bedrooms).

If the deal can't pay your expenses and you think it's the best you can do, then you and your agent should share in the disappointment (in the proportions you agreed upon).The only difference between your financial obligations like property taxes and your contractual obligation to your realtor, is that you are in a position of power relative to the agent and not the county that collects your taxes. 

I want to make sure that the test and control files are similar and at least do not significantly differ from each other for my key variables.The Test & control files will be the same size splitting the total file using a random number generator.I then plan to measure the key variables using T-Test for each of the two files to make sure they pass the critical value 0.05. (95% significance).However, I have been asked to either a) ensure proportions are maintained, i.e gender (Stratified Sampling) or b) make each file almost the same by sorting on the key variable and selecting every 2nd record as the Test file Queries:1) Can I still use T-Tests to measure the similarity / difference between the key variable within the file or do i now need a different stats technique and if so what should i use?

I would go on apartment search websites and see how long units were listed, proportion of inventory that was occupied with renters, etc.That helped me make some decisions as well. 

There were walkways where trash including things like plastic milk jugs were compacted by the owners feet.

Finally, is the necessity for and Owner's Policy (if any) proportional to the equity the owner has in the property, i.e., stands more to lose?

Makes me curious to know if one must proportionally split the carryover basis or if there are options there as well?

You spend a little more and don't get quite as much increase in rent in proportion to the additional acquisition dollars but a solid house in a better area with a more stable working class/middle class tenant while still cash flowing is worth it to me. 

Whereas in truth, interest paid on the total principal that has been "fronted" to them is the same proportion of the balance - every year (eg. 4.5%)!
