Many investors will, at some point as their portfolio grows, determine that time has become their constraint and outsource the management and maintenance to allow them to continue growing their portfolio and/or focus on more profitable uses of their time.That is why it is wise to factor it into your calculations from the beginning.

It's wise for investors to remember that in the short and intermediate term, investing is volatile.

@James Wise thanks for sharing specific information sources!

Hello,in many areas i have research, show prices are much more doable than where i am located (north jersey) while i keep searching for my duplex to house hack here, would it be wise to buy an SF or duplex in a market like Orlando or Jacksonville or even NC where job growth and property taxes are low and numbers work out better for cash flow instead of holding cash?

Grateful to @James Wise and his team for helping me find the perfect property within both my budget and risk tolerance. 

your filling the GAP between the first lender and purchase price  ergo slang for equity loans is gap funding.25% apr is what yo need not 25% total return other wise yes time erodes your return.. 

@Stone Jin I have found quality tenants through Facebook Marketplace but I agree that percentage wise there are better quality leads through the other sites. 

Interest rate environment - in the still low historical interest rate environment, locking in as many 30 year fixed terms as possible is wise I believe. 

Yes, this is very wise!

Condition wise both will start to degrade but the market appreciation will likely outpace this condition depreciation.The BRRRR unit (assuming good rehab) is likely to rent for more than a small new ADU.So the BRRRR after refi will cost you less (especially as a percentage of total value), will result in more rent, and likely appreciate similar to the RE with the ADU.The key is to do the BRRRR right starting with finding the good candidate RE at the right price.
