It seems best practice right now is to work out a payment plan and also put the tenant in touch with any state, county or city support available to tenants to help them pay rent.Thank You for your response,I did put in payment plan of $900 monthly for the last three month and i only got $150. 

In expensive areas finishes are at a premium that is disproportionate to their cost, for example a granite or quartz countertop and new kitchen cabinets cost maybe $10k to put in but in an $800k house they may command a $30k-$40k premium over a home with a 1970s kitchen, I'd go for dated but functional and do the upgrades yourself, much more value that way.2.

You can take all the principle you put in after 5 years of having your account tax free.

Put up gutters, grade the land with a cat 5 to slope down at sharper angles from the house, and put in some of the 80lb home depot concrete bags (the super strong stuff) in any problem areas.

Personally, I pay out of my pocket for all of those up front and recognize I am at risk of losing all those funds.If you do not have the cash, you would need to find someone that wants to partner up with you, ideally before you put in an LOI. 

@Tommy McGraw Condos are good to put in if the target market will be buying them as a primary residence.

I want to be able to put in the 10-20% for hard money interest-only payments and then also the refi at 5% for the mortgage to see what it all looks like.

I was considering having duct-work put in and replacing the original installation.

There was never a vapor barrier put in place under the home or gutters along the roof.

You could offer them an option to pay a fee in place of rolling the dice on your ability to re-rent it (I think a lot of management companies do this), but I think if you tried to put in a fee like that it would be voidable by the court.
