It makes for a a very unpleasant stay and very unhappy customer.

Most custom home builders I know in my market are 1.5-2 years on their builds right now.

Source custom-cut 1.5" minimum diameter rods that are continuous length (not the expandable ones as there is usually a gap in the metal that fabric can get caught on).

It's clear they're making a couple of dollars on the float while screwing their customers. 

Others have adeptly highlighted the potential challenges in this scenario.

I did this exact strategy when I worked in sales, and I can assure you I never received a phone call from a potential customer.

I am a Realtor in the North Atlanta market and have a client looking to build a custom home.

Dominicexactly, i had an out of state client asking so i think it's important to highlight it  

Figure a few grand to paint rooms, replace carpet in a room, deep clean and spruce the property, replace a fixture or two, etc.If you have to replace your resident annually the $9600 total income will get a gut punch.The true value of the higher-end neighborhoods is residents know if they move out of the home they have it's a challenge to find another, especially if they have been there a few years and have a competitively rewarding rent rate.All this really is is basic economics...sell ten custom widgets for $1000 or 100 standard widgets for $100 each.

Yash,Underestimate the incomeOverestimate the expensesWay too many investors get caught up in the "highlight" prospects of a deal and don't do any "risk analysis" so to speak.Start from the worst case scenario and if you can absorb such a scenario.Then consider the upsides.It's a good way to go about underwriting deals.Wishing you much success
