Maybe instead of dumping more money into the marketing, you just need to allocate the current spend to a different target that yields higher commissions.  

I spoke with my real estate lawyer and he said to look out for complaints from tenants about noise and the inconvenience of having contractors coming and going.The tenants have a toddler and an 8-month old.The only pros I think would be to lock them in for at least a year and the finished basement would increase my house value.Cons would be that the money they give would be allocated to the finishing of the basement and I would need to set aside money to pay down my monthly operating expenses.Any feedback would be appreciated.

Capital also has a funny way of allocating itself to opportunities, wherever they may be. 

So his cash flow when allocating for all expenses is negative.  

Yes some business will shutter before they can re-open, but this should present opportunity for new businesses and the labor should re-allocate.

I would use over 3x your allocation.

For example, developing neighborhoods or luxury properties requires strategy and planning alongside connections to reputable sources that can allocate a quality build.

I also plan to allocate time to explore alternate deal-finding avenues beyond the MLS, including probate listings, foreclosures, vacant properties, wholesalers, turnkey, etc.
