Would love your insight and/or simple list of pros and cons.For Baselane I'm interested to hear if folks have opened an account with them and what that looks like - are you immediately transferring to an existing property account or actually using their account to manage things?

So you are doing construction in your yard, but not directly connected to the existing structure the tenant lives in and they are already complaining?

Midterm Rental calculators don't exist because the mass data is hard to pull right now.

There could be a lot of new builds going up in the outskirts of a city, but existing properties in the city closer to amenities may still be desirable. 

Essentially there are investors out there that can build a large enough portfolio with little debt that can cash flow enough for a great life.If you want to scale to many properties then you will want to consider leveraging your existing properties.

I understand home designs are pretty expensive, and cannot just be applied to any lot/existing neighborhood.

The majority of states have NOT enacted any rules, regulations or legislation that has altered the “wholesaling” landscape.  

As @Chris Seveney mentioned there is not really enough equity in house 3 to get a meaningful LOC. even if you were able to leverage enough to pay off House 2 the new rate you would be paying would be higher than the existing mortgage, so you would still be behind overall.Your ROI on those payoffs vs keeping money in index funds is not very good either.Lastly, remember that cash flow from rentals can seem good until it’s not.

In my market zoning ordinances often make 95% of existing residential lots nonconforming where nothing could be built within the ordinance.

They lend you the money you need to buy their house.Subject to - you buy the house subject to the existing mortgage.
