and what would this do to my credit score? 

Others will disagree with this...and that's fine.In my opinion, the key to success in real-estate is not avoiding downturns (which is impossible because no one can accurately predict when and how badly...and trying to time also often results in missing good deals too)...but instead structuring conservatively to *expect them* and be able to hold through them (not lose the property) and get out to the other side.

These lenders often have more experience and flexibility with properties that include ADUs and JADUs.Community Banks and Credit Unions: Local community banks and credit unions may be more willing to work with you, especially if they have a better understanding of the local real estate market and the value ADUs and JADUs bring to a property.Mortgage Brokers: A mortgage broker may have access to a wider range of lending options and could help you find a lender willing to consider your property.

If those numbers do not fit FIs, then it is likely bad investing strategies or one has an unrealistic outlook on living standards.The example takes into account to average cash flow of $200-300 per rental.

The problem is that there are so many factors that impact the rate...credit score of the guarantors, Loan-to-Value, property type, citizenship status, etc...the list goes on.

Many people try it and get bad education (which is often over priced) Think of it like any profession, it takes a lot of work and effort and you need a good mentor / teacher - it also doesn’t happen overnight.

Anyone get a bad review for not having them? 

So are you saying four hours of sleep is a good thing or four hours is a bad thing? 

Upon checking out the home, I felt comfortable offering 240k and no credits due to my prior experience of checking out homes in the area.

@Spencer Elliott- 1) any chance you can leverage  any other properties  2) keep trying the local / smaller  banks and  credit unions for the builder to get  approved  3)  have you  tried  " builders  capital " ?
