Rents are under market and expenses could use a trim.

The advice above is average.

Renovated a house-hacked but because of the income, we could not deduct expenses  Should we put all our properties in an LLC?

To me interest rate is just another expense like insurance and tax.

meant to say we have two financial regime right.the last 12 years are the cheap money regime, so buying real asset risk/reward is almost no brainer than holding cash, good to become borrower for asset that's appreciating (10%) lolbut in the last 12 months we moved to expensive money regime where holding cash itself is producing money with almost no risk, while doing business including real estate is having higher risk (compare to cheap money regime).

The average investment is around the $70K mark.

This criteria is for 1-4 and 5-8 unit programs.I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23DSCR lenders generally let you vest either individually or as an LLC.

We average less than 30 days on the market, but some homes are more challenging to rent than others. 

We've thought about subbing out to a proper "property management" company but we really don't need help collecting rent or expenses (this is all done electronically online) or even finding new Tenants on the odd occasion when we have an Apt turnover (we use Brokers for that) ...

It's a real expense at the lake.Good Luck!
