Too many investment loans effect my ability to buy my home?

[Mushfiq S.]

I currently have 1 investment property. My father is my partner in all deals (we go in 50/50). He insists, since I do not have a primary home, that I do not take many loans. So we have been trying to maximize properties under his name so it does not affect my Debt to Income and ability to buy a home personally.

I do have plans to purchase a personal home in 5+ years.

My question is: if I can show positive cash flow from all my properties in two years' tax returns, will that decrease the debt liability to underwriters? 

I want to purchase investments but also one day settle down somewhere. What is the best strategy for this?
