As an example I have spoken to many and have volunteered to share lessons learned from notes, private lending, or any other type of real estate and first questions are “what will you pay for referral fee” or it costs X to speakWhen I tell them I am not selling anything - they don’t care.

I don't think that makes sense unless rates are really low. 

We always choose low maintenance materials for rehab in our class C/B properties.

I am guessing it was just the extreme low temps.

These can at times offer lower than average 30 year fixed rates, eliminated PMI requirement, lower down payment requirements,  and closing cost credits.

I saw many pre approved ADU partner cost over $250k plus site prep for 500sqft deatched ADU.

Maybe i can get seller assist with the closing costs or seller financing on the deal?

Unless your mechanically handy your maintenance costs will eat you up.  

You can do this all at once if your state has a low cap (rent for our units has a late fee applied on the second) or if you're allowed a larger late fee you can apply it in stages 1/3 on the second, 1/3 on the 7th 1/3 on the 11th. 

I purchased the property in 2022 with my VA Home Loan, so I have a very low interest rate of 2.75%.Long story short, we've finished renovating and stabilizing rents (for the most part).
