This was a decent size project, but it took 3+ months which seems much too excessive. 

Unfortunately it is attached to the main house, but that would likely be the highest grossing unit based on size.

It can be a couple thousand bucks for a survey and an application to hundreds of thousands or more depending on the size.

Also is the loan type recourse or non-recourse, short term bridge or long term financing and what size loan you look for?

@Mendy Blasberg greetings from another Cincinnati investor.What size properties are you looking at?  

Looking at the chart this seems far from healthy.

If the property is appreciating, but you're crediting your percent ownership based on the original purchase price, you're getting an out sized return in later years.

For example, One of the very few properties in the neighborhood with master suiteHas open layoutBigger lotOver-sized garagebigger bathroomsSome times we will provide an appraiser with our actual budget, but always with a lot of pictures.

Your partner would need to satisfy the mortgage brokers  liquidity requirements, have the net worth equivalent to the amount of the loan and someone on your team will need to provide information that they have 24 months of experience with Fannie Mae and Freddie Mac loans and have managed properties of equal or greater size.  

I owned a condo for about 20 years and my taxes were low compared to other units (same size) that had been sold over the years.
