If I had multiple STRs I would probably have to go to a more professional accounting system.How do you communicate with the renters?  

The benefits of online funds would be ease of communication, deal flow, lower minimums, easier to vet with more eyeballs, more diversification, etc.Ideal Investment:I invest $10k-$50k into a each deal.The property is Bought, Renovated, Rented out then Refinanced.I get back all or most of my $10k-$50k.We keep the monthly cash flow.

I like the other responses - but also be honest and communicative.

@Michael Henry, I think if it were me, I would want to know what other *needs* might be lurking... could you ask them to communicate anything that they are aware of that may need attention (with the shared understanding that you may not be able to get to everything immediately)?

If you are getting financing and you are the guarantor on the loan then you deserve some additional consideration.Then determine the value of General management such as: paying certain bills, communication with property manager, accounting, working with CPA on tax reporting.Then calculate the final returns for yourself and your investors. 

Terrible communication and very unprofessional.

Did you figure out where you will be getting all your materials from so you can communicate directly if any contractor needs supplies?

It's hard to even be sure your communication attempt ever reached the intended target.

In some cases the reasoning makes sense to me, as a property owner myself: it's not a smart business practice to rent to a tenant who is only in the country under a short-term status, who does not have proof of sufficient employment, who does not have a guarantor (we'd often just call them a co-signer in the US), and with whom the landlord cannot communicate (if the tenant doesn't speak good Japanese). 

The property management firms in my town run the gamut from a few large managers that do a decent job with Appfolio, communication, etc.
