I guess this also depends on how many rentals you have and what features you require in a PMS.

It depends on the month for myself. 

I live in Clermont and depending on where you are looking $200 will be pretty tough to find at all.

Depending on how bad it gets the fed will step in and fire up the money printer, of course that would be after a big bank fail and/or massive layoffs.

Depending on the cash flow for the property, you are looking at up to 75% of the appraised value. 

Remember to always budget 10-25% (depending on age/condition) extra as a buffer.

It depends, we recently had a deal where we got under contract for $26k, We new AS-IS there was a strong possibility to sell it on market for $95-100k.

Depends.

It will depend on what your goals are, but if you'd like to scale fast, you could leverage the $100k cash to buy 2 or 3 duplexes in lower priced markets that have higher rent/price ratios.You could use these properties to learn the ins-outs of OOS investing and use these to build your network and confidence in the market.

As far as the size I think it would depend on the space.
