I don't remember the exact figure, but what surprised us was how similar their cost came to the stick built home we chose.  

I think these neighborhoods have the potential to be high demand destination rentals due to parks, the lake, nightlife, easy transportation, etc. 

I am working with the city for approval and have a cost estimate from someone I know of 250k to build another duplex on the property and eventually multiple duplex.

Building costs here are astronomical.

This could result in lower financing costs.

I want to start searching for properties to make offers, but I need to know how to estimate repair costs.

Buying backlinks of almost any kind is often considered at the least Grayhat, potentially black hat depending on how the links are built. 

If the market changes or costs go up, etc., your flexibility is limited and interest keeps ticking. 

After everything was fixed and they listed the unit, apparently they claimed that I was not allowed to have any understanding of who would be renting my home due to potential bias and discrimination (this is the first time I have not been able to view applicants general profile (credit score/occupation(removing any identity markers)), but fine, I let them choose the tenant and so far there hasn't been any issues.

Our intent was to sell, but we are not having luck and need to move in another direction, carrying costs are draining us.
