@Ryan FoxAny CPA who gives you a numerical answer is making some assumptions, most likely generic and incorrect. 

I think I'll save more by using an experienced local architect that can provide contractor contacts and cost-saving design features and products (like windows, doors, finishes, etc.).

Hi Aliya, Look for recently sold properties that are similar to the subject property in terms of size, condition, location, and features.

Numerous ways of getting this done, lets connect!

Make sure you are continually tracking properties for sale in your market, what is selling for how much, what features are in demand and so on.

Ensure that all information about your property, such as square footage, building features, amenities, and any relevant factors, is accurate.

I also get numerous leads by paying a 1,000 finders fee for any unlisted property someone tells me about that I buy.

Calculator should provide amount of conversion  tax payments needed, one or multiple conversion options,  Medicare IRMAA impacts, various investment percentages of Roth growth vs IRA growth, and RMD amounts with associated tax bill.I’ve seen numerous CFPs hawk their services for $5,000 or more.  

By "partial" I mean renovating the kitchen and bathroom, painting the place, re-tiling the floor and maybe adding some smaller features that can make a difference to prospective buyers, such as new A/C units, new internal doors, or maybe even sell the place furnished (home staging is not really an option here); with no or minimal demolition, and hopefully without electricity or plumbing issues.
