I know my general area I live is expensive compared to most of the U.S. 

Would you guys want to meet up some day to have a chat about the Belgian property market and compare notes perhaps in Brussels?

But these expenses are 100% necessary compared to a lawsuit that would subject my other 10 properties from any negligence from the 1 that may have an issue.  

But compared to other markets I have considered Frederick and Washington County seem to be VERY SLOW.

Your best bet is to call around and present your question to local banks, small local credit unions, and the national SFR buy-to-rent finance companies such as B2R, Colony and Firstkey and compare terms, rates and fees.  

If someone can get a comparable unit for $700, they're not going to pay $800 and certainly not $850. 

Your point about response rates in wholesaling is a good one- it makes more sense to compare something that is very similar.  

I don't qualify for a loan mod or refinance my income is way way way to low compared to this expensive townhouse.    

Our maintenance expense in newark historically runs about 10% The 6 family buildings can be the toughest to manage and fill as compared to larger 10+ units or 2-3 family homes.

But, when you compare that property to the market you do not add or subtract values to the subject, you do that with the comps bring the comps in line with the subject property.
