I would waste little time tracking down a loser.Our time is much more valuable creating the future.Franklin

I was thrilled to get that deal, I thought it was slightly under market value then (today it rents for $1800 or so, according to a website that tries to track the last time it was listed publically).I had wanted to rent in Cambridge, but I felt priced out, the best 2 bedroom apartments I could find were around $1700.

Track everything you do and review that regularly to help you decrease your expenses increase your income.  

@Jonathan Santa Seems like you're on the right track.

I don't know what tax line mapping means, but we have a due to/due from our set up on our balance sheet that allows us to track owner distributions and infusions.

Investment properties are a min 20% depending on credit and track record you may have to put up 25% plan for either.

Some will ask you to provide an appraisal or some will order one on their own.All will most likely want you track record on how many flips you've completed.

When tracking specific areas for a while you can almost estimate 100% what are you going to be able to rent a property for.  

I would not use Venmo for rent collection since they have transaction limits and also it's hard to track. 

Once you have some type of track record, you might be able to get others to back you.
