I reviewed about a dozen options.

I feel more at ease losing this deal and finding my client a better option.

@Ana Maria A Self-Directed Roth Solo 401(k) is a great option for real estate investing if you're looking for tax-free growth and withdrawals in retirement.

I do ground up development and new construction and land entitlement in Columbus Ohio in hotel, multifamily, single family spec, and build to rent so normally we would talk to an intermediary and walk them through the options and together you could make the decisions. all of these are built 25% below market. the triplexes cost 395k to build and rent for $5400 a month. 

Of course, I totally understand that you wouldn't want to do if that guide is written by another real estate agency, in which case you have option 2.b.

I would check and see how many 1 bed and 2 bed options there are and what they are priced at because most folks will prefer the full place to themselves so rooming 2 people together could make getting bookings a bit more difficult (not always the case but something to consider)

Do we have trusted advisors, brokers or community bankers within this platform who would like to work on this?

BTW - Are you using both platforms?

You’ve taken strong steps by hiring a reliable cleaner and listing the property across multiple platforms.

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!
