Typically a bank will not do any cash out on a purchase mortgage because there is no equity for it. The selling price of the house will be at or close to market value for the house and your mortgage amount plus your down payment will be equal to the selling price. As someone earlier said, you can give them less of a down payment and save that money for solar, but keep in mind that if you put less than 20% of the house value down you will likely need to pay PMI which could be as much as $100 a month(or more) depending on the amount of the loan. If you’re OK with the PMI then a lot of banks will go as high as 97% loan to value or maybe even as much as 100% loan to value, so you don’t need to put any cash down, but I don’t think anyone will loan you more than the house is worth and have you start upside down on your mortgage.
You say that you’re going to move in in August, but you’re going to close in 45 days. The actual move in date is less important than the closing date. If you close in July, for example, you could still have Tesla start the permit and install process as soon as you own the house, even if you haven’t moved into it yet. However, you won’t be able to get too far along in the process until you have actually closed on the house. You do need to be present on install day, so if you are moving across the country that might be a little difficult if you haven’t actually moved yet, but you might be able to delay the actual install until you are actually in or near the house.
In my case, after I put down my deposit it took Tesla only a day or two to come up with the initial drawings showing panel placement. Once I approved those it took another couple of weeks before they got to the point where they were ready to apply for the permit. My city requires signed and sealed engineering drawings for permits and I think some of the delay there was waiting for those drawings to be completed, signed and sealed. Different cities have different requirements.
At this point the process would have to stop until you actually own the house since they won’t be able to get a permit until you have closed and the house is in your name. The other thing to consider is that you probably don’t want to apply for any solar loans before you have closed on your mortgage. It is possible that additional inquiries or loans appearing on your credit report before you close on the mortgage could cause your closing to be delayed or potentially even cause your mortgage to fall through at the last minute.
If you want this process to move as quickly as possible, what I would do is the following:
Go ahead and place your order and put down your $100 deposit. Let them come up with the drawings and approve the drawings. After that they will ask if you are paying cash or going with a loan. If you tell them that you are paying cash you might be able to change your mind and go with a loan later, so maybe ask if that’s a possibility, but as I said above, I wouldn’t apply for the loan until after you have closed on your house.
So the process will likely be put on pause at this point as the next step will be to get the permits and that can’t be done until you have closed and actually own the house. Once you do close you can apply for the loan and Tesla can go ahead and pull the permits. At closing ask the closer for a copy of the warranty deed. You won’t show up in the public records as the owner of the house for around 30 days after closing, so that could cause confusion when they apply for the permit. If they provide a copy of the warranty deed at the time they apply for the permit that should allow it to go through.
The permitting process may take a few weeks, then once the permit has been obtained they will call you to schedule the install. If you can arrange to be at the house on install day, even if you haven’t moved in yet, then go ahead and schedule it to happen as soon as possible. (In my case they called me the day after the permit was approved and scheduled the install 19 days out). If you aren’t going to be near the
house until you move in, then schedule the install day for a couple of days after move in day.
They don’t want other contractors working on the house on the same day as install day and I assume that would include movers, even if you are moving on your own. They wouldn’t want people underfoot walking in and out of the house all day with furniture and boxes while they are trying to do the install, so don’t schedule the install on move in day.
But I think that’s probably the way you’ll be able to get it installed as quickly as possible
