I like the idea of value adds, but ADUs are not an optimal path.

By built correctly I am referring to SEO (search engine optimization), and the website programming.

.- diversification - better chances of optimizing your results in terms of risk, cash flow and growth- Taxes.

I feel buying and holding a rental managed by a property manager in the IRA could have a higher yield, but one would not be able to use deprecation to their advantage, so one year flips make more sense (instead of 1031 exchanges for tax optimization).   

However, installation costs and procedures may vary, so it's worth getting quotes from both if you're not doing the work yourself.As a hard money lender specializing in fix and flip deals, I've seen successful investors use a mix of these sources to optimize their budgets while maintaining quality.

Are you marketing it like a professional listing and is the listing fully optimized with professional pictures, title, description, etc?

Evaluate the rental market in your area to determine the optimal configuration for maximizing rental income.The choice between using cash flow from your current house to cover expenses or pay off the mortgage faster depends on your long-term financial goals and risk tolerance.

I share your optimism but I am not sure this means we are out of the woods yet in terms of rates.

Typically over 5+ units 25% down is optimal but 20% is possible..I don't think I'd recommend a property management company for your search, likely a multi family focused investor RE broker and strong nationwide lender.

If you could see an optimal layout, then perhaps you could pick and buy your own furniture if you knew the inventory needed.
