I contacted a local insurance agency where the rental is located and got a reasonable price. 

Agency - as expected, always the best rate and lowest fees.

Rent collection apps like Rent App can help, but Venmo may lack the needed features.

Further, too many groups coming together can mean too many cooks in the kitchen and lack of the ability to execute the biz plan properly.You bet on the jockey first. 

Rents for apartments and single family homes are up significantly, and I don’t see that trend ending any time soon: we are severely lacking in housing and available inventory.

If I have a buyers agency agreement but this property is off-market, is this binding?

I've personally worked with a handful of "investor-friendly" lenders, primarily on DSCR loans in recent years, and each time I've run into significant delays, lack of transparency about the process, have been fed the requirements in a piecemeal fashion (every few days there's a new random request rather than having it all organized from the start), and have even run into lenders who were substantially misinformed about the real estate industry or the laws that govern it on both a local and federal level.I think there should be a better site to encourage accountability by tracking how long it actually takes each lender to close their loans on average, and what unexpected hurdles investors encounter when trying to work with them.I can't seem to find such a site.

Lots of information, agencies and resources.

They need the insurance declaration pages (1-2 pages showing the annual premium and the insurance agency contact info), property tax bill, and mortgage statement. 

Current property manager appears to be unresponsive and also seems to lack work ethics.Looking for recommendations of reliable, professional and responsive property manager who manages in those areas.
