HI Stephen,You can always open HELOC or line of credit from your primary house or non primary house, assuming you have sufficient equity and income to qualify.

You are off to a great start because you know you don't want to LEAVE your job to do real estate, you want real estate to be a sufficient side car to the job you are already crushing out of the gate.

We are already surrounded on three sides by urban zoned homes.My neighbors and I have been approached by two individuals, one is a neighbor who is a real estate agent, and the other one a friend of a neighbor, who works with a real estate attorney; both individuals asked us to join them in working with the 5-6 developers they have approached.

For instance my 90 lot subdivision at one point I had 90 legal descriptions and parcels on one master deed.. as I sold them off we just deeded them out separately.. its super common especially in older platted cities were lots might have been small like 25 X 100 and someone bought 3 of them and then built one home on all three.. some places they force merge them others you can go back and recreate the Old lots of record.. there is millions upon millions made by those that know how to find shadow plats and bring to life underlying parcels.

Dedicate sufficient working capital to your business 6.

@Michelle SharkoAnswering questions in step by step fashion:- Is it a good thing to do or not is a personal finance decision and it depends on the person asking it, their risk tolerance which in part has to do with how this HELOC or line of credit works and how your personality fares relative to taking on new debt (a person more adverse to debt might have sufficient savings and temperament to pay down/back the debt versus a financially liberal person might get in over their skii's as).

Quote from @Karl Kauper: In my 20+ years as a landlord in three different states, it’s my experience that the owner can screen more effectively and find tenants way more quickly. 

We are in the top three Map rankings on google.6.

This will give you an idea of where you can be priced at with factual data rather than guessing a 3%. 3% could be sufficient but the data will help you be confident in your decision. 

It would be best if you had a timeframe in place for initial reports of uncleanliness or broken items, maybe three days, but the truth is that all complaints are relevant no matter the time.
