If you are having trouble finding applicants I would recommend adding to to facebook, groups, and more.

So we are using SmartMove for the application process.

Beyond maintenance a good PM software will auto assign late fees, e sign leases, have integrated applications and leasing and much more!

Keep in mind, if the subdivision is not by-right and your investment group wants to seek a variance, you are able to do so as the equitable owner meaning you don't have to purchase the property before submitting your zoning application, receiving your refusal and appealing to the ZBA.

I’m leaning towards just continuing with the higher application syndications, roll all the liquidity events and cash into new deals.

A lot of the pm softwares offer the ability to have applications sent out for screening.

CR will cover rent assurance for 3 months but beyond that its on me. i'm now 7 months vacant on one property and i'm told the city has denied the application for Section 8 b/c there are "too many vacant properties" in the area.

HOWEVER, consult with your lawyer and/or property manager to verify the applicability of the law. 

Not a lot of applications but rejected some out of caution.

...if the vacancies are frequent or extended, it can be a big expense, so I analyze this thoroughly.As for house-hacking specific costs, there are things like furniture/appliances/decor for the common areas of the house, costs of screening applicants (like background checks), cost to advertise, the time and effort required to manage a house hack, etc.  ...although these expenses are worth consideration, they tend to be much smaller and almost inconsequential compared to the big capex expenses that can come with buying the wrong property (e.g.; you might spend a couple hundred bucks on tenant screening, but a new roof might cost $20k+).Back when I was house hacking regularly, one of the most significant "costs" was the cost of my time and effort to acquire tenants (which includes all the time and effort of posting ads, responding to inquiries, answering questions, doing viewings, screening applicants, managing tenants once they were in-place, etc.).
