The other non-math issues I'm good handling myself. 

Where another issue arrises is I recently quit my job after becoming pregnant as they would not cover my maternity while overseas, my husband is employed however he works for a UK company and is British so would be unlikely to help us with the situation in the US.

It is what is left after snow removal, cutting the grass, utilities, tenant issues, parking lot issues, property taxes, mortgage payment, etc. that make a difference.

They seem to have a good team but this is something not thought out it seems , in their support I do have DSTs which have had the same issue and have not been making payments. 

If it is only one flip for now, I suggest you find a CPA just to advise you on State filing requirements, ensure you are claiming all write-offs and issuing 1099s, etc.

No DTI issues.

There are several other issues (undisclosed maintenance markup fees, excessive charges to our account, significant reductions to agreed rent without communication, etc).

Are you aware of some actual legal authority that validates the IRS opinion on this issue?

I just learned that builders risk and liability insurance coverage can cease once a CO is issued for a new build.

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