In comparison to personal residences, investment properties may demand additional documentation and underwriting requirements from lenders; nonetheless, a credit score of 730 is generally regarded as acceptable and may qualify for advantageous loan conditions.

With that said, it doesn't me it can't be something that the right person wouldn't be able to take care of.

Not $30, 40, or 50 MM but in the Bs, then personally i wouldn't be first.

@Josie Sevilla, Lot of personal preference. 

Note that you can only get a chase card if you haven't applied for 5 personal credit cards in the last 24 months.

Would a cash out refinance to a LLC factor into my personal DTI?

Even if you buy the right property, managing the rental and tenants can literally destroy your finances, sanity, health, family life, etc.Keep educating yourself and keep trying!

We are not a wholesale company and we are looking for deals that we can close on personally.

Other methods do too, but I can personally vouch for this one. 

Initial budget $250-600k +- Please advice if it's seems like an ok plan in your opinion (preferably if you have personal experience).
