Crime was way more than it was shown in city database as most of the things were never reported.Actual rent collection was only $4200 by 18 tenantsPark had very bad repo in area (Which was known to us)What we did after buying:Worked on road (new milling road), removed extra trees, cleaned 40-50 dumpster of trash.Worked with city development agencies to remove bad tenants via evictions or stationed police officers on weekend to deteriorate drug traffic, incentivized good tenants to provide us video /call cops with videos so that cops visits are frequent.Removed bad homes and brought in 7-8 newer homes from other parks.Repaired around 19 houses in last 18 months and brought up average rent $680 per home.

If you have a good relationship with a bank and you have even break-even numbers on your rentals, there's usually a solution to be found to acquire more properties. 

You can also check your own FICO at myFico.com and start to clean up any errors. 

I'd consider partnering up with someone and offering management, lead generation, cleaning, turning, renos, etc for either free or a low rate to understand the game and build up that network.

Tell them the property will be in better shape than with long-term tenants because it's getting cleaned 1-2x per week. 

Even if you were to fully automate, still need someone to reset the units and clean them up. 

We keep a very clean job site throughout the build, or at least as clean as these things can be. 

Assuming your hard money lender wont offer the rehab budget with the loan (which might not be the best option anyways), a decent option (if your business has been around long enough) might be to try and qualify for 6-12 month interest free business credit cards, which could be a short term solution, however if you have some property with equity, in my opinion a HELOC would probably be your best bet.  

Minimum credit score 700 No evictions/ clean backgroundincome at least 2.5 times the rent.

There aren't many options that provide the full suite of services (cleaning, guest communication, etc) you need to operate successfully.
