Realistic refi LTV expectations

[Matt Y.]

Hello,

Thanks in advance for any comments. I've been following the posts here for a while and while some offer valuable insight I'm hoping to get situation specific advice.

In general the plan is to buy a SFR for 800k with 10% down. After purchase, have an ADU built and rent it out. I have about 200k max to facilitate the building the ADU - and will be the first to admit that I have no idea if this is high or low so please forgive my ignorance here (learning as we go).

From there the hope is that the property value will have increased in value due to having two units. What I'd like to do at that point is refinance out to keep myself as leveraged as possible. While I will have funds in reserve outside of real estate endeavors, I would prefer not to have them sitting in equity.

In a situation like this, I'm curious what the best I can hope for on the LTV is for both OO and as an investment property. From what I've read recently, it seems that the best I can hope for is 75% LTV on the cashout refi unless I find a regional bank.

Thank you,
