I just don't think you can blindly choose one vs the other without knowing the numbers behind the rental currently and what you plan to do later (is there a larger renovation upcoming?)

You have to explain to the architects that this project is to serve as a retirement plan for your mother in law and the main goal is it should bring profit, they may change plans and build very simple

By doing a refi for a larger amount than I currently have but still keeping 20% in the home, I realize that I need to time this with the next property.

I have a decent budget for a down payment for several units and I was thinking of starting with something like the following...Unit type: Condo (only looking at turnkeys; not going to rehab - much)Asking price: $182,000 - would offer $160,000Fair rent price: $1,600/moProperty taxes: $2203/year; $184/moHOA: $223/monthMortgage (P&I): $635/moLandlord insurance (estimated): $20/moOptional considerations:Property management: $160/mo (10% of the rent; I am not going to use property management at first; I will manage it)Vacancy: $160/mo for as long as it is vacantRepairs: $80/mo as neededI obtained the optional numbers above from here:https://www.biggerpockets.com/renewsblog/2013/01/1...This comes down to...Worst case scenario of $138/month given vacancy, property management, and repairs.Best case scenario of $538/month without any of the optional considerations - so hopefully this is the profit I would be looking at almost every month.Thoughts?

And you’re probably wondering, “How can you make a profit offering full market value?”

When I wanted larger projects and larger apartments.

It will take more work, but that's why it's profitable.

Have a separate signed agreement that you will be responsible for half of the mortgage payment the entire time the house is owned and due 50% of profits from a sale. 

Below is the formula that I plan on using:MAO = ARV - Repairs - Fixed Costs - Profit - Wholesale FeeWhat I need is someone who is willing to show me exactly how to estimate ARV, repair costs, and fixed costs so that I can accurately determine the price for both the buyer and seller. 

How do "Investor Friendly" RE agents make a profit from wholesalers?
