You'll build this before buying the property anyway.

Following ethical and professional guidelines helps build a strong working bond with agents.

One of my clients did a rehab on a two-unit building in Bridgeport that appraised for $100k over within in a year.

My considerations have been: adding a small laundry area, building out the bathroom for a larger shower, making a separate parking area, building a walkway, putting up a fence so they have some privacy/yard space, mini split on the AC...

Build a small amount of capital and buy first investment.  

A big part of my success was building good ties with brokers.

For the first property I did, I had someone in the building meet the deliverymen and paid them a small fee for their time.

Lenders typically want to see 2-3 new builds completed within a 12-36 month period, depending on the lender.

Then with the equity you build up through loan paydown and appreciation over the course of a few years you can cash out refinance and use that money to snowball into another property.

Then you owe ABOUT 0.009% per year of the building value per year you should have taken depreciation. (25% tax on 3.636364% of the building value you depreciated.)good luck.
