My own work has not had dramatic fails, mainly because I don't rush it.

In my experience, when residents have unexpectedly high heating bills, they gripe about it, their ability to pay rent is reduced(leading to a higher eviction rate,) and they tend to leave the apartment at the end of their lease, dramatically increasing turnover.

My income dramatically jumped 3X from my last job. 

Those fees dropped dramatically once expedia was involved. 

You can use your 1031 with mortgages as you were anticipating to buy whatever assets in whatever quantities you want to complete your 1031 and boost your ROI.  

If you want primarily medical profession tenants, it will dramatically narrow down the number of buildings that would work for you. 

Thanks for the boost.

After I bought my first one the market conditions changed dramatically with prices shooting up.

One large area of interest really is trying to figure out the best way to obtain funding without paying too large of fees that the deals no longer become worth it, but at the same time, I feel like if I stick to conventional investment loans, I am putting 25% down, which ties up a large amount of capital, and more than that, I am forced out of all cash offers and short closes which dramatically limits my opportunities, which is not wise.

Vacancy dramatically low in many many markets.
