The main downside is being dependent on the HOA—issues like poor management, rising fees, or unexpected assessments can hurt your investment.

Next, I tend to recommend that clients stay away from inflated HOA fees.

HELOCs are usually variable rate and there may be yearly fees associated with maintaining the HELOC.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

.)- All in Cost = Cost to build * Square foot  - Sales Price = All in Cost + (All in cost * 20%)* Covers contractor and soft cost on either fee based or cost+- Profit = (Sales price - (Sales Price * 7%))* - All in Cost   accounts for agent fees and closing cost- Initial List Price = Sales price + 10%      A buffer to test market absorption- Break Even being All in cost, point where everyone is paid except me. - List price is to test the market absorption at "x" price. 250k land + build.

Also, this would only remove the mortgage debt itself from your DTI if it was to work; you would still be hit with a liability for the annual taxes, insurance, and HOA fees (but also receive the benefit of the rental income).

If anything explain that there is a fee on top of a lifetime charge (which on its own is kind of weird), but okay. 

I am in PA and yes, it is legal to charge late fees to your tenant regardless of Section 8 subsidies or not, provided the tenant's lease allows for them.

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.
