You should not be using someone else's prices (or Kukun's algorithm), you should be using your own prices from your local contractors and using the specific material selections you picked for your project.Here's an example of how bad some of the data is in Kukun and why it's not practical for investors that are wanting to create accurate estimates for their projects:I just added "Exterior Doors" to my project, and I was told that 4 single doors and 1 double door is $59,352 in Kansas City, MO which is 20x what I would actually pay as an investor.I believe the above was a bug, but nonetheless there was no way for me to fix this issue or understand why or how it was calculating this value.In summary, you don't need a fancy algorithm to tell you what something costs, you just need to know basic math and have a general understanding of how much materials cost and what contractors charge for specific repairs.For example, if I have 5 exterior doors I need replaced (4 single entry doors, 1 french patio door) this is how I would estimate the costs:- Single exterior doors labor 4 x $250/each = $1,000- Single door material 4 x $300/each = $1,200- French patio door labor 1 x $400/each = $400- French patio door material 1 x $750/each = $750Total = $3,350Add 25% profit for your contractor and the quote should be around $5k for 5 doors.The hard part is finding out what your contractors charge, after that it's just basic math that you can do in a spreadsheet.

If you purchase via an IRA (as opposed to a 401k), you will need to open an IRA account at a specialty trust company which allows for investments in real estate.

A few examples would be: carpet, tile, staircase handrails, exterior materials etc. 

Most people I’ve worked with prefer a single asset “fund” set up for the project as opposed to a true multi-asset fund.

They would be a valuable resource for making something like this work as opposed to a big bank.

Having said that though, I have found that while the volume of people looking to rent may be less in February as opposed to August or September as an example, they tend to be more serious. 

@Matt Moore, take a cut off to a local lumber yard (not HD or other big box) and ask if they have a matching profile for exterior siding.

The association that I am apart of charges a $230 dollar monthly association fee, which covers ALL exterior maintenance (except the doors and windows), water expense, gas expense, snow removal, lawn care, trash removal, repair on common lines like sewer/gas/electric, and all liability outside the structure.

For me cash flow is important , I don't mind selling it for a lower price fast as opposed to waiting 6 months.

So for you I would compare what you are going to pay in housing for him anyway as opposed to what it cost to buy the condo.
