There are lots of hard money options (or maybe not "lots" but not too uncommon) with no appraisal required - that makes the offer equivalent to cash (closing within a couple days and no appraisal contingency - its out there)The lender still has to ok the deal, appraisal or not.

Some types of Creative Financing include: Seller/Owner Financing, Land Contract, Wrap, Assumption, Subto, Lease Option, Contract for Deed.

Typically people charging for that service are doing it because they need the money...if you catch my drift. 

However, if managing tenants isn’t something your parents want to deal with, selling after renovations could also provide a large profit.Feel free to reach out if you'd like help with running numbers or considering financing options if you go the ADU route → I’d be happy to help!

Quote from @Drew Sygit: We give our tenants as many options as possible - EXCEPT picking up their rent.Exactly.

You don't have to spend a fortune and buy a house directly on the beach to do well, but your starting price point for a viable option in this market is around $350-$450k for a solid 2-3 bedroom oceanfront condo or around $500k for a 3-4 bedroom house within walking distance of the beach. 

I can help you with financing options and help you analyze deals.

We're open to various options, like house hack, multi-fam, BRRRR, etc. 

There are more options, but this is sufficient to answer your question. 

And use all of the proceeds from the sale in your purchases you'll defer all tax.This does give you some interesting options because you can allocate those proceeds anyway you want.
