Tenant seasoning will be required for a bank refinance.

I'm guessing the lender will require 6 months of insurance and taxes up front at closing for an investment property which will drive the closing costs up considerably. 3.

Add in the saved time and avoided headaches and hassles of self managing, and you'll find the cost is well worth it. 

I would recommend that once you set your rental requirements (And if you haven't, make an actual list) do your best to STICK to them.

Obviously fix and flip and BRRR is the mainstreet strategy because people seem to avoid new build and ground up construction as people say it's "expensive" but I want to hear from someone who has done it themselves.

You probably already know all this, or at least should but the last paragraph under landlord must give 30+ days notice (all must end at month end more than 30 days out, not exactly 30 days.) says there are legal requirements for tenant’s to give any notice.

(Yes plenty of my acquisitions are "wrecks" as you call it, and require significant expense to be made great...). 

After speaking with Lender, their requirement is experience doing Ground Up construction.

Real estate can provide a more tangible asset and potential for rental income, but it requires more management and can be less liquid.

I would definitely hire a management company if I plan to rent the property.Back up plan is to stay there two years, sell the property and avoid paying taxes.Fellow BiggerPockets community, I would love some advice on evaluating whether I should flip the property to reinvest in a bigger home or multifamily unit or rent the property with a management company?
