You have a number of issues in your post unfortunately.

Since Landlords are going to be monitored even more now with the price gouging issues surrounding the fires in LA, I would be extra cautious.

3) If their handyman can't handle a repair issue and they have to hire outside contractors, many PMC's will then charge a markup for their time - but they don't tell you this upfront or disclose in their management contract.

Will having money fix that issue?

There are cheaper one’s in D/F areas but I would be careful as those can create a laundry list of additional issues.

Any repair issues the new acquisition has you will feel to much greater magnitude due to the property carrying a lot of debt.

If I had an answer to my money issue then I would quickly pull the trigger on a good deal. 

How can I correct cashflow issues if I have 3 properties?

Here in TN we issue POQ within a couple of days of rent being overdue, usually giving them 14 days to correct before official eviction proceedings start.

No DTI issues.
